Development of a plastic injection molding training system using Petri nets and virtual reality

INTRODUCTIONAt present, plastic as a substitute for metals in products is the most important mainstay in industrial raw materials. Furthermore, plastic injection molding is one of the most common and versatile methods for mass production of complex plastic parts with excel-lent dimensional tolerance. Since the technology of injection molding has been widely applied in manu-facturing, training on injection molding is of great importance. The traditional approach is to consult some technica…     

THE DEVELOPMENT OF A COMPETENCE SCALE FOR LEARNING SCIENCE: INQUIRY AND COMMUNICATION

The objective of this study was to develop an instrument to measure school students’ competence in learning science as part of a large research project in Taiwan. The instrument consisted of 29 self-report, Likert-type items divided into 2 scales: Competence in Scientific Inquiry and Competence in Communication. The Competence in Scientific Inquiry scale contained 4 subscales: presenting questions and hypothesis, planning, experimenting and data gathering, and data analyzing, interpreting, and concluding. The Competence in Communication scale contained 4 subscales: expressing, evaluating, responding, and negotiating. Students were recruited randomly from primary, junior, and senior high schools in different regions of Taiwan to validate the instrument and establish its reliability and validity. The results of the analyses indicate that the instrument, scales, and subscales have reasonable internal consistency; that the theoretical structure was supported by empirical data; and that the subscales are homogeneous. These results indicate that it is an appropriate tool for measuring students’ competence in learning science. Implications and suggestions for further studies are included.

班级的『柔性』管理

与普通高中的学生相比，职中生具有以下明显特点： ①一部分学生入学成绩处于中等或偏下水平；②因拥有一定的专业特长，故在心理上有着强热的社会认同感；③因接受的是职业教育而存在着一定的自卑心理。生活上我行我素，情绪易大起大落；④自我管理能力较强，独立意识明显；⑤因升学压力较低且兴趣爱好广泛。故班级缺乏凝聚力；⑥与社会接触较多。拥有较强的社交能力。但也易感染一些不良社会风气。[第一段]

Two ancient rounds of polyploidy in rice genome

An ancient genome duplication (PPP1) that predates divergence ofthe cereals has recently been recognized. We report here another potentially older large-scale duplication (PPP2) event that predates monocot-dicot divergence in the genome of rice(Oryza saliva L.), as inferred from the age distribution of pairs of duplicate genes based on recent genome data for rice. Our results suggest that paleopolyploidy was widespread and played an important role in the evolution of rice.

延续性护理对脑卒中患者知信行的效果研究

目的:探讨延续性护理干预对脑卒中患者知信行(KAP)功能康复的效果。方法:选择我院神经内科收治的脑卒中患者110例,随机分为对照组和干预组各55例。对照组采用神经内科常规护理,干预组在常规护理基础上联合延续性护理干预,通过对脑卒中患者的知识、态度及行为,比较两组的护理效果。结果对照组和干预组患者知信行问卷的总体得分,比较差异有统计学意义(P<0.05)。结论:通过延续护理干预方式对脑卒中患者的知信行功能康复起到治疗作用,纠正不当的生活行为,提升日常生活能力,明显改善康复锻炼的依从性。
