随着科学技术、网络技术迅猛的发展,许多互联网业务如网上求医、网上购药、网上保健也日渐火热,成为人们防治疾病的又一手段。网络医疗是网络科技与医疗技术结合的产物,在信息高速发展的今天,它已成为医学交流中一道亮丽的风景线,各国都在不遗余力发展自己的远程医疗系统,这无疑将推动医学模式的进步。然而作为一种新的医疗手段,网络医疗目前仍存在着诸多的弊端和问题,这些问题反过来又可制约网络医疗的发展,因此必须在技术、政策、法律各方面予以完善,使之更好地服务于人类。 相似文献

病人的治疗结果取决于医生治疗方案选择的好坏,然而,为获得最佳的治疗方案,医务工作者需要有可靠的研究证据支持。循证医学以及Cochrane协作网和其它多种循证资源,作为一种新的获得高质量医学证据的方法和途径,在肿瘤学研究中起到了重要作用。在循证肿瘤学领域有很多组织提供高质量的指南,然而,循证肿瘤学以及基于循证证据的指南仍可能是有暇疵的。 相似文献

王弼易学有三个特点,即条例义理化、形上本体化、具有内在性。朱熹在少年时用数年时间研习立于官学的王弼易学,从而受到了王弼易学思想的深刻影响。王弼的太极学说是朱熹太极本体论的思想渊源。 相似文献

本研究旨在从人们的生育态度中探讨中国人思维方式对传统性与现代性有何影响。研究分两部分:第一部分用相关研究的方法探讨思维方式与中国人的传统性与现代性的关系;第二部分设计了一个能够反映中国人传统性和现代性的情境问卷,通过测量人们的生育态度,来进一步证实思维方式对传统性和现代性的影响。通过对257名被试问卷调查结果的分析发现:思维方式和中国人的传统性与现代性之间有着密切的关系,对情境问卷的进一步分析发现思维方式和情境因素一起影响人们的生育态度。研究结果对我们理解中国人思维方式的影响有着重要的理论和实际价值。 相似文献

This study examined whether a virtual avatar could be perceived as a real human by patients with mental disease, especially schizophrenia, as well as whether a virtual avatar could be applied to acquiring patients' behavior characteristics in a short conversation situation. The virtual avatar has been used for various applications which need to communicate with other person or to train or educate by showing humanlike behavior. Recently, many researches have shown that the virtual avatar technology has been enhanced and the avatar could be perceived like real human. A virtual avatar, standing in a virtual room, was designed for this study. Tasks to approach, initiate a talk, and answer to avatar's questions was assigned to the 11 patients with schizophrenia. As behavioral parameters in the virtual environment, the interpersonal distance and the verbal response time were acquired. In addition, the Positive and Negative Syndrome Scale (PANSS) for patients was administered in order to investigate the relationship between patients' symptomatic characteristics and behavior parameters. The interpersonal distance was negatively correlated with the negative syndrome scale, a subscale of PANSS, which is consistent with previous research reporting the relationship between interpersonal distance and a real person's image. The verbal response time, however, was not correlated with any other subscale of PANSS. After analyzing subitems of the negative syndrome of PANSS, two positive correlations were found: one was with blunted affect and the other was with poor rapport. We concluded that the virtual avatar could be perceived as a real human by schizophrenic patients and the avatar could draw the schizophrenic patients' behavior characteristics. 相似文献

The purpose of the study was to determine if the CAAS could be used with middle school students. Currently no study has been done for the application of CAAS on middle school students. We examined the reliability and validity of the Career Adapt-Ability Scale (CAAS) in Macau for middle school and high school students. The CAAS consists of four scales, each with six items, which measure concern, control, curiosity, and confidence. We tested the internal consistency and factor structure with 270 middle school students and 188 high school students. We also compared students' performance on CAAS in terms of gender and age. The results indicated that internal consistency estimates for the subscale and total scores were good for both high school and middle school students. The factor structure was quite similar to the one computed for combined data from 13 countries (Savickas & Porfeli, 2012). In addition, we found that high school students scored significantly higher than middle school students on the CAAS scales. Based on the results, the CAAS-Macau Form appears ready for use by researchers and practitioners who wish to measure adaptability resources among middle school and high school students in Macau. 相似文献
