工科学生工程安全素质培养的探索与实践

高等学校工科学生的社会职业定位是工程师,工程师的主要工作是从事工程的规划、设计、实施、运行和管理,其工程行为对工程安全具有至关重要的影响。随着现代工程向大型化、综合化和复杂化方向发展,工程安全已成为人类社会面临的重大问题,解决工程安全问题的根本途径之一是加强和改进高等工程教育,致力于提高工科学生的工程安全素质培养。对工科学生的工程安全素质培养,各高校可根据自己的专业优势和服务需求面而独具特色,以适应社会对工程安全人才多样性要求。湖南科技大学在工科学生的培养中,从培养目标的改革中加强了对工程安全素质的要求;从培养内容的改革中加强了对工程安全知识的传授;从培养方法的改革中加强了对工程安全技能的训练;各项改革中的措施在实践中取得令人满意的效果。     

Incidence rates and risk factors for injury events in high school students in Lijin County, China

PROBLEM: Most investigations of injuries among Chinese populations are focused on urban or better developed areas, fewer on rural or poor areas. METHODS: From September 21 to 27, 2002, an epidemiological investigation of eight kinds of injury-related events was carried out among 1,944 students in 39 classes randomly sampled from middle schools in Lijin County, a rural area. The eight kinds of events were: (a) traffic accidents, (b) poisoning, (c) fall, (d) burn or scald, (e) blunt or sharp tools contact, (f) electrical contact, (g) animal or insect bites, and (h) non-fatal drowning. RESULTS: The total incidence rate of eight kinds of injuries in the previous year was 21.1%. The incidence rate among boys was 24.2%, while that among girls was 17.4%, which was significant (chi-square=13.4, P<0.05). The incidence rate among junior high school students was 23.1%, while that among senior high school students was 15.5%, which was also significant (chi-square=13.2, P<0.05). A case-control study of 410 students with at least one of eight kinds of injury events indicated that students' gender and their mothers' health status were related to their injuries. CONCLUSION: The injury incidence rate in a rural area was less than other results in urban or developed areas. Students' gender and mothers' health status were important factors associated with the occurrence of injury. IMPACT ON INDUSTRY: In order to improve the surroundings of the growing population of adolescents, some preventive measures should be put forward, especially to the high-risk students of injury.     

大学校园土壤中重金属污染研究

为研究大学校园土壤中重金属污染的状况,在西部某高校校园中选取10个采样点,分别采集了表层和下层土样,分析测定了土样中Cu,Zn,Pb,Cr四种重金属的含量。实验采用了微波消解、火焰原子吸收分光光度法对土样进行测定。结果表明待测校园土壤中重金属含量目前处于安全的范围,但大学,尤其是高等科研院校,应妥善处理科研试验过程中产生的污染物,为大学学生提供一个安全的大学校园环境。     

Evaluation of noise environments during daily activities of university students

Noise conditions specifically in areas inside university facilities and its impact on the quality of life of university students are topics that have received little attention. This paper presents a study of the noise conditions in which university students of various institutions in Madrid, Spain, carry out their daily studies. A representative number of measurements was carried out using noise dosemeters and dataloggers in order to evaluate the levels of noise, noise dose and exposure to noise during school periods and extracurricular activities. The results were compared with the recommendations given by current environmental noise regulations. This paper was complemented with a survey to get to know how students perceive the exposure to noise in university environments.     

高校食堂清洁生产行动方案的研究

高校食堂是高校建设的重要环节之一,清洁生产能更加有效的管理高校食堂.文章以南京某高校食堂为例,通过问卷调查和实地考察的形式,分析高校食堂各个过程能耗比例和污染物产生的原因,并且对高校食堂电消耗、一次性消耗品和固体废物提出具体措施.结果显示:清洁生产每年平均节约电费1.25万元;减少一次性用品并且每年平均增加收益2 058元;平均减少剩饭剩菜14.83％.

Critical pedagogy of place to enhance ecological engagement activities

Scientists in higher education institutions around the globe recognize the importance of engaging with public stakeholders to share their enthusiasm, explain their science, and encourage primary and secondary students to enter the sciences. However, without direct consideration of students’ and teachers’ perspectives and interests, scientists may design activities around their own goals, limiting the impact on school stakeholders (i.e., students, teachers, paraprofessional staff, students’ parents, and other caregivers). We drew from natural and social science research to describe how expanding the conception of place beyond the biophysical can help engage school stakeholders in meaningful ways. We describe the multidimensional PLACE framework that we developed to integrate perspectives, knowledge, and values of all stakeholders in engagement programming. The framework is organized around topics that stakeholders should discuss early on to ensure successful partnerships. We recommend that scientists identify and use pedagogy that is inclusive; language framed around dialogic communication methods; aims and motivations centered on engagement; cultural funds of knowledge of place (i.e., disciplinary, personal, or experiential knowledge); and evaluation of engagement based on meaningful metrics. Two case studies are presented to illustrate how the PLACE framework components, when addressed, can lead to robust, successful partnerships between scientists and schools.     

大兴安岭地区中小学生人体数据调查与分析

通过对大兴安岭地区中小学生身高调查发现,该地区中小学学生的平均身高要高于《中国卫生统计年鉴》（2008）中同龄青少年的身高平均值,学生视力随年龄增长而下降。因此有必要为学生配备与其身高相匹配的课桌椅。     

基于CiteSpace的高校教师职业心理健康文献计量分析

为系统把握高校教师职业心理健康领域近10年的主要研究内容和研究方向,以中国知网(CNKI)作为数据源,经过2次检索得到2011—2020年10年间的文献,统计分析发文量,使用CiteSpace软件可视化处理,得到关键词共现图谱。结果表明:高校教师职业心理健康的相关研究主要集中于职业倦怠和职业压力,研究热点是成因和对策,重点研究对象为体育教师、青年教师、英语教师和女教师;通过内容分析发现,职业压力和职业倦怠均对高校教师职业心理健康存在消极影响;从社会、学校、个人3个层面有效干预可改善教师职业压力和职业倦怠,进而提升其心理健康。
