月经间期与人流术后即时放置吉妮柔适环使用12个月临床效果观察

目的观察月经间期与人流术后即时放置吉妮柔适环的临床效果。方法随机抽取月经间期与人流术后自愿放置吉妮柔适环的236例受术者,分别于放置后1、3、6、12个月进行随访,观察其一年内续用率及副反应有何差别。结果人流术后即时放置吉妮柔适环与月经间期组副反应无明显差别,因症取出率低于月经间期组。置器满一年的118例人流术后即时组续用率为96.61%,因症取出率为3.39%;月经间期组12个月续用率为95.73%,因症取出率为4.27%。结论人流即时组放置吉妮柔适环免去了二次手术的痛苦,值得临床进一步推广和应用。

HR in the small business enterprise: Assessing the impact of PEO utilization

Within small businesses, organizational leaders are themselves often responsible for the HR function, an area where they typically have limited training and experience. Not surprisingly, small business leaders have raised concerns about the quality of HR programs in their firms and the fact that HR consumes scarce managerial time. While professional employer organizations (PEOs) emerged in response to such concerns, much controversy exists as to whether and how small businesses benefit from PEO utilization. Using a survey of more than 740 small businesses, we examine the relationship between PEO utilization and two key small business outcomes: managerial time required by HR activities and satisfaction with HR outcomes. Our results indicate that firms not using a PEO reported significantly lower levels of satisfaction with HR outcomes than firms that used a PEO for a limited set of transactional services and firms that used a PEO for both transactional and strategic HR services. Among firms using a PEO, satisfaction with HR outcomes was significantly higher among firms that obtained a broader set of transactional and strategic HR services. Firms that used a PEO also reported that HR consumed significantly less managerial time relative to leaders in firms that made no use of a PEO. However, there was no significant difference in the time demanded by HR between firms that used a limited set of transactional services and those that used a broader range of transactional and strategic services. Implications for the role of PEOs and their use within small businesses are discussed. © 2005 Wiley Periodicals, Inc.
