我的研究生涯

在黄昆先生30寿辰时，新加坡的World Scientific出版社用英文出版了黄昆先生的论文选集：Selected Papers of Kun Huang。黄昆先生为选集中收集的20篇论文专门写了一篇《注释》，看过该选集的同志都认为《注释》实际上总结和介绍了黄昆先生一生中作研究工作的经历和经验，对所有从事科学研究的同志，尤其是年轻同志，很有教益，建议《物理》杂志将《注释》释译成中文发表，后来我们了解到，北京大学的张树霖教授已将《注释》译成中文，在张树霖教授的支持和帮助下，《注释》的中文翻译稿经黄昆先生校订并征得他本人以及World Scientific出版社的同意，现在本刊“特约专稿”栏以“我的研究生涯”为题刊登，以飨读者。     

Psychosocial Impact of the Teacher''s Voice Throughout the Career

It is generally accepted that vocal performance decreases with age. This decrease can be expected to be more pronounced in voice loading professions, which may lead to occupational dysphonia. The aim of this study was to investigate the course of voice complaints, experienced handicap, and absenteeism of work due to voice problems throughout the teaching years. Questionnaires were distributed among teachers of primary and secondary education, and 1875 were analyzed. The questionnaire was designed in such a way that personal aspects and questions about periods with symptoms and absence from work were included. The Voice Handicap Index (VHI) developed by Jacobson et al was sent along with the questionnaire. Surprisingly, a significant decrease of voice complaints during the career of the teachers was observed. The expectation that the percentage of teachers with a history of voice problems should experience more psychosocial impact, measured with the VHI, along their professional career could not be confirmed by this study. These results indicate that serious attention has to be paid to teachers with voice complaints. The fact that teachers in the beginning of their career complain more than in the end of their career emphasizes the importance of adequate aimed prevention programs for future teachers and for starting teachers with regard to their voice.
