ABSTRACT
BACKGROUND: In recent years, researchers have been paying increasing attention to the issues of how emotions affect people's perceptions of the environment, and how they influence people's behavior or intentions to act. The purpose of this study is to explore the influences of emotions on environmental intention to act by using the neuroscience technology electroencephalography (EEG). METHODS: A total of 70 university students participated in this study. They looked at positive and negative emotional environmental pictures and decided if they wanted to protect the environment after looking at the pictures. The participants wore an EEG cap throughout the process in order to collect their brain wave (EEG) data. RESULTS: The analysis of variance (ANOVA) results showed that the power value of meditation was significantly higher when the participants looked at the positive than at the negative emotional environmental pictures (p < 0.001). The power value of pressure was significantly higher when the participants looked at the negative than at the positive emotional environmental pictures (p < 0.001). The power value of attention was significantly higher when the participants looked at the negative than at the emotional environmental pictures (p < 0.001). CONCLUSIONS AND RECOMMENDATIONS: The findings showed that positive emotional environmental pictures might promote positive emotions, but will decrease the intention to act to protect the environment. In contrast, negative emotional environmental pictures will increase negative emotions, and will also increase attention and intention to act to protect the environment. Implications of the findings are discussed.

AIM: We investigated the association between type 2 diabetes mellitus (T2DM) and periodontal disease (PD) in the context of the current periodontal aetiology model. MATERIAL AND METHODS: In total, 14,747 community residents aged 35-44 years were invited to a community-based PD survey between 2003 and 2006 using the community periodontal index. Significant factors modifying the association between T2DM and PD were ascertained. We further assessed the association between T2DM and the risk for PD, within strata of significant effect modifiers, after controlling for other putative factors. RESULTS: The prevalence rate was 10% higher in subjects with T2DM than in those without. After controlling for significant factors, T2DM was positively associated with the risk for PD (adjusted odds ratio=1.34,95% confidence interval: 1.07-1.74). The results of interaction assessment showed that only the waist was identified as a statistically significant effect modifier for such a positive association. CONCLUSIONS: The association between T2DM and the risk for PD among young adult was demonstrated. This finding, together with other aetiological factors, fit with the current hypothesized model of the aetiology of periodontitis. However, the effect of T2DM modified by waist measurement should be verified in future studies.

OBJECTIVES: As periodontal disease preponderates in adults, early detection and interventional regime is urgently needed. However, there is lack of evidence-based data on evaluation of population-based intervention programme related to periodontal disease. The aim of this study was to assess the efficacy of intervention regime on early periodontal disease identified from a community-based periodontal survey. METHOD: By randomization, 60 subjects were allocated to the intervention group and 49 to the control group respectively. Status on periodontal disease of participants was evaluated at entry and re-evaluated after intervention at 1-month and 18-month follow-up respectively. Primary outcome evaluated was based on Community Periodontal Index and Loss of Attachment on sextant level. RESULTS: The efficacy of intervention was significant in Community Periodontal Index (P<0.001) but not in Loss of Attachment (P=0.53) at 1-month and 18-month follow-up. CONCLUSION: The improvement of periodontal disease owing to intervention regime was seen in Community Periodontal Index but not Loss of Attachment as yet at 18-month follow-up after intervention.
