RESUMO
AIM: To investigate the influence of television programs on children's mental growth so as to evaluate advantages and disadvantages on coordinative development of TV programs and child education.METHODS: A survey about the quality and audience rating of children's TV programs was carried out at the Developmental Psychology Institute of Beijing Normal University.RESULTS: The television programs have three main functions for children: education function (or learning function, orientation function), information function and entertainment function. Main purposes and effect for watching TV by children are: ①The major two are entertaining and getting information to enrich their knowledge, but other purposes like training thinking ability and learning skills still exist. ② Children TV programs can promote learning knowledge, skill, and academic study; develop intelligence and personality. Problems mentioned above have the age differences. However, the negative effect on child should not be neglected: ① A lot of unhealthy contents block children's healthy development. ②Watching TV for hours wastes a lot of valuable time that can be used for other important things like reading. This time-killing habit may harm children's profound thoughts and thinking ability.CONCLUSION: We should present new philosophy on children's TV programs producing. The producer should know well about children's needs and respect their requirements, including all kinds of rights and ideas, linking the entertainment function of these programs more closely with their education function and taking advantage of successful business models oversea, and inspiring organizations to produce more suitable programs.
RESUMO
BACKGROUND: Most of previous researches on the emotion regulation ability only took children as objects.There were very few studies to investigate the adolescents' emotion regulation ability.There are fewer researches tried to study over-province large sampling to get general situation of Chinese adolescents' emotion regulation ability. Very few studies have taken emotion regulation as independent factor and explored its developmental rules OBJECTIVE:To analyze the characters of grade and gender in emotion regulation ability of Chinese adolescents DESIGN:Cross-sectional sampling survey questionnaire with adolescents as subjects SETTING:Institute of Developmental Psychology of Beijing Normal University.PARTICIPANTS:Totally 11 855 students from junior and senior high schools in Beijing,Henan,Chongqing,Zhejiang and Xinjiang, 13 high schools are included.METHODS:The present study uses "the adolescents' emotion regulaPsychology Institute, Beijing Normal University) as measuring tool to grouply test with the class as a unit. The tests in the 5 districts were completed within 2 weeks. The questionnaire is a 5-point scale.The level of emotion regulation is the mean score of the 14 items. And the higher points means higher level of emotion regulation.in emotion regulation between different grades of adolescent.RESULTS:Main effect of gender is not significant (F(1.11843)=0.040,P=0.842),while main effect of grads is significant (F(5.11843)=101.437,P=0.000),and interaction effect between gender and grades is significant (F(5.11843)=3.812,P=0.002).CONCLUSION:The emotion regulation ability of adolescents increased with the increasing grade but being stable after grade 11;the girls' emotion regulation ability exceeds the boys' gradually in grade 11,and there is no difference in the emotion regulation ability between boys and girls in grade 12.
RESUMO
Objective To evaluate the effect of ultra-filtration extract from Danggui Buxue Decoction (DBD) on immune function of H22 bearing mouse and explore the mechanism through observing the effect of ultra-filtration extract from DBD on the secretion of the cytokines (IL-2,IFN-?).Methods We used membrane separation technique to extract DBD.The content of IL-2 and IFN-? in splenocyte culture supernatant was detected by enzyme-linked immunosorbent assay (ELISA),and the mRNA expression of cytokines (IL-2,IFN-?) in splenocytes was assayed by reverse transcription-polymerase chain reaction ( RT-PCR).Results The content of IL-2 and IFN-? in splenocyte culture supernatant was increased in ultra-filtration extract from DBD groups,significantly in high-dose group (P
