Opis:
This study aimed to investigate the subjective health complaints (SHC) in the teaching profession of Hong Kong. On the basis of the SHC inventory, a questionnaire was prepared for data collection through a mail survey. A total of 1 710 usable questionnaires were returned by the primary or secondary school teachers. The results showed that 99.5% (n = 1 702) of respondents suffered at least one type of the 39 single health problems on the total SHC scale during the preceding 30 days. The 10 most frequently reported health complaints among the teachers were tiredness, eyestrain, anxiety, sleep problems, voice disorder, shoulder pain, neck pain, headache, cold/flu, and lower-back pain. With the exception of the category of pseudoneurological complaints, primary school teachers showed a statistically higher prevalence in reporting problems in 6 of 7 subscales. The 5 most severe complaints were tiredness, eyestrain, sleep problems, shoulder pain, and voice disorder.

Opis:
This study investigated the effects of user factors and cognitive sign features on the guessability of mine safety signs. Sixty naive participants guessed the meanings and rated the cognitive sign features of 42 Mainland Chinese mine safety signs. The results showed that some user factors were significant predictors of guessing performance, while some were not. As expected, guessability scores varied significantly with the cognitive sign features of familiarity, concreteness, simplicity, meaningfulness and semantic closeness. The findings emphasize the need to create awareness of the importance of mine safety and promote understanding of mine safety sign meanings amongst people in their work environments. To design more user-friendly mine safety signs, industrial designers should develop and evaluate signs with consideration of the significant user factors and the 5 sign features tested here.
