In vitro remineralization of hybrid layers using biomimetic analogs

Resin-dentin bond degradation is a major cause of restoration failures. The major aim of the current study was to evaluate the impact of a remineralization medium on collagen matrices of hybrid layers of three different adhesive resins using nanotechnology methods. Coronal dentin surfaces were prepared from freshly extracted premolars and bonded to composite resin using three adhesive resins (FluoroBond II, Xeno-III-Bond, and iBond). From each tooth, two central slabs were selected for the study. The slabs used as controls were immersed in a simulated body fluid (SBF). The experimental slabs were immersed in a Portland cement-based remineralization medium that contained two biomimetic analogs (biomineralization medium (BRM)). Eight slabs per group were retrieved after 1, 2, 3, and 4 months, respectively and immersed in Rhodamine B for 24 h. Confocal laser scanning microscopy was used to evaluate the permeability of hybrid layers to Rhodamine B. Data were analyzed by analysis of variance (ANOVA) and Tukey’s honest significant difference (HSD) tests. After four months, all BRM specimens exhibited a significantly smaller fluorescent area than SBF specimens, indicating a remineralization of the hybrid layer (P≤0.05). A clinically applicable biomimetic remineralization delivery system could potentially slow down bond degradation.

Chinese middle school teachers’ preferences regarding performance evaluation measures

Teacher performance evaluation currently is receiving unprecedented attention from policy makers, scholars, and practitioners worldwide. This study is one of the few studies of teacher perceptions regarding teacher performance measures that focus on China. We employed a quantitative dominant mixed research design to investigate Chinese teachers’ preferences for teacher performance measures and the possible reasons for their preferences. Considering the quantitative results, the surveyed Chinese teachers identified fulfillment of additional roles, collaboration with faculty and staff, and students’ test scores as the most important measures for performance evaluation. Qualitatively, the most important measures that the surveyed teachers reported were the teacher’s morality, workload, and students’ test scores.     

黄州城区中学学生对体质健康测试认知与态度的调查与研究

通过文献资料法、问卷调查法和数理统计法等方法,对黄州城区部分中学学生的体质健康测试的认知及态度进行了调查与研究,结果表明:大部分学生参加体质健康测试的目的较明确,能够认识到自身健康的重要性,测试后愿意加强身体锻炼。但同时也存在一些问题,如部分学生对测试的成绩有一定的质疑,体质较差的学生对测试的抵触及耐力测试项目不受学生欢迎等,并提出了相应的对策。     

职业教育项目课程的几个关键问题

本文重点论述了当前比较关注的四个热点问题,即什么是项目课程,项目课程是否忽视理论知识,项目课程与CBE课程有什么区别,现在是否具备了项目课程改革条件。澄清这几个问题,既有利于消除一些迷惘,又有利于使课程改革进行得更加平稳。     

论教育管理的规范与创新的融合

教育管理的规范与创新是当前教育管理体制改革所要面临的两个方面，二的有机结合是提高教育管理水平的基础。因此，在教育管理体制改革的过程中，我们必须正确理解教育管理的规范与创新的主要内容及其相互关系，并尽可能使二有机融合，从而提高教育管理水平。     

非平衡多阶段物流系统建模与优化方法

首先提出了参数化界面分布的新概念,将一个非平衡多阶段物流系统转化为多个相互独立的单一阶段物流系统,然后采用Prüfer数对每个阶段上的物流模式进行编码.通过一种改进的解码方法,任何一个随机产生的Prüfer数都能够被解码为一个与物流系统的节点容量相匹配的可行的物流模式.基于这2点创新,建立了一种新的基于参数化界面分布和Prüfer数编码的系统建模方法,相应的遗传算法称为PIP-GA方法.与st-GA方法相比,PIP-GA不但具有更好的优化结果,而且需要的计算时间更少;虽然所需的存储空间有所增加,PIP-GA仍然是一种有效而稳健的非平衡多阶段物流系统建模与优化方法.
