Objective To improve mental health of children in the rural area by intervention with moviewatching.Methods The participants were 438 students from Anhui province,including 273 students in grade 5 from two primary schools and 165 students in grade 2 from two middle schools.Subjects were randomly divided into two groups:an intervention group with movie-watching (n=188)and a control group(n=250).Results The inter-group difference between the pre-measurement and the post-measurement on depression and anxiety of the intervention groups and the control groups in grade 5 from two primary schools was not significant,while the intergroup difference between the pre-measurement and the post-measurement on value8(the intervention group (2669.52±2216.43),the control group(316.57±1410.83)),and the inter-group difference was significant(t_(values)=10.721,P=0.000).The inter-group difference between the pre-measurement and the post-depression, anxiety and values of the interntion groups and the control groups in grade 2from two middle schools was significant(t _(depression)=2.046,P=0.043;t _(state amxoetu)=3.507,P=0.001;t _(trait anxiety)=3.392,P=0.001;t _(values)=5.022,P=0.000)respectively).The intervention effect on mood of depression,anxiety and the values of intervention groups in grade 5 from two primary schools was not significant,while significant on values(F=91.62,P=0.000);while that of intervention groups in grade 2 from two =0.000 respectively).Conclusion Movie-watching intervention wag an effective way to improve middle school students' mental health and to develop correct values.Movie-watching should be an alternative way to improve met-al health of children in rural area for its operability.

Objective To investigate the relationship between social network behaviors and personality.Methods Both questionnaires including self-reported Renren questionnaire and the simplified Chinese version of NEO five-factor inventory (NEO-FFI) were completed in university students (n =509).Results (1) Individuals with higher score of Extraversion used Renren applications more frequently,such as using Wall (2.26 ± 0.51,2.10±0.40,t=3.163,P=0.002),Status Update (2.58 ±0.71,2.33 ±0.62,t =3.268,P=0.001),Image (2.05±0.88,1.81 ±0.72,t=2.628,P=0.009),and Photo (2.17 ±0.49,1.96 ±0.33,t=4.409,P＜0.01).(2)Individuals with higher score of Openness of Experience were more likely to use Gift (2.01 ± 0.49,1.83 ± 0.59,t =2.870,P =0.005).(3) Individuals who were willing to use Blacklist (41.93 ± 4.41,43.07 ± 4.72,t =2.207,P =0.028) and who were willing to send private messages (42.23 ± 4.79,43.27 ± 4.55,t =2.476,P =0.014) have higher score of Agreeableness.(4) Individuals who checked messages more often had higher score of Conscientiousness (41.59 ± 6.33,40.72 ± 5.67,37.56 ± 8.33,F =7.170,P =0.001).(5) Individuals with higher score of Neuroticism were more likely to be dependent to Renren (2.91 ± 1.01,2.48 ± 1.02,t =3.815,P ＜0.01).Individuals who were more likely to express their emotions on SNS had higher score of Neuroticism (33.10 ± 6.78,32.19 ± 6.16,31.36 ± 5.77,F=3.594,P =0.010).Conclusion The data suggest that the usage of social networking sites are related to personality factors.Personality can be used to predict university students' social networking behaviors.

Objective To investigate the relationship between personality and social network profile-based information.Methods 438 college students were recruited,and Big five inventory NEO-FFI was applied to all subjects.The participants' Renren web profile information were recorded.Results ①Individuals with higher score of Extraversion had more friends (2.47 ± 0.29,2.34 ± 0.27,F =17.861,P =0.000),shared more (2.51 ± 0.56,2.32 ± 0.57,F =8.617,P =0.004),pasted more photographs (2.30 ± 0.51,2.14 ± 0.56,F =5.523,P =0.02).② There was a U shape correlation (t =2.258,P =0.024,t =2.115,P =0.035) between levels of neuroticism and numbers of blogs (0.66 ± 0.71) and photographs (1.92 ± 0.83).③There was no difference on numbers of friends (2.38 ± 0.31,2.39 ± 0.27,F =0.149,P =0.700) and e-gifts received (1.30 ± 0.52,1.26 ± 0.45,F =0.257,P=0.613) between participants of high and low levels of agreeableness.④ Individuals with higher scores in openness shared more with others(2.46 ± 0.57,2.29 ± 0.58,F =5.248,P =0.023).⑤ Individuals being more conscientious had more blogs(1.08 ±0.49,0.96 ±0.48,F=3.064,P=0.082).Conclusion There are significant differences about profile-based information among college students with different personality.

Objective:To develop an integrated intelligent device of measurement and calibration for cardiopulmonary resuscitator,so as to improve the efficiency and reliability of measurement and calibration of cardiopulmonary resuscitators,and to ensure the safety and effectiveness of rescuing wounded.Methods:This device used modern sensor transmission technique,and adopted a systematically combined design with industrial control measurement and control module.This device could realize simultaneously automatic detection for a series of parameters included depth and frequency of pressure,single breath frequency,moisture volume and so on in the device of measurement and calibration.Results:The measurement and control of the measurement and calibration device of the integrated cardiopulmonary resuscitator are accurate,which average values of pressure depths were respectively(29.8±0.13)mm,(49.3±0.08)mm and(69.89±0.14)when standard values were respectively 30,50,70 mm.The pressure frequencies were respectively(79.30±0.08)times/min,(99.89±0.14)times/min and(119.94±0.24)times/min when standard values were respectively 80,100 and 120 times/min.The moisture volumes were respectively(347.99±2.77)mL,(546.18±1.89)mL and(746.67±2.14)mL when the standard values were respectively 350,550 and 750mL.The above results of this dive are consistent with the results of the standard device,and the errors of depth and frequency of pressure,and moisture volume were respectively±15%,±10%,±20%,which all were within the allowed range.Conclusion:The measurement and calibration device of integrated intelligence of cardiopulmonary resuscitators can complete various detection of related parameters within one pressure cycle of the cardiopulmonary resuscitator.The detection results of the device are highly consistent with those of the standard device,and the detection results are accurate and reliable.
