It proposed to increase the awareness of the safety of teachers and students. And it should have a rational organization of teaching. It also should increase financial input on a regular basis in the field and equipment maintenance. Specialized security agencies and establish safety management systems and contingency plans, to encourage students to participate in accident insurance, guarantee learning the sports teaching activities of the security.展开更多

The students enrolled in the class chose to study the theme Brazilian Public Politics. After several debates regarding the theme, the students were separated into three groups and each group chose a subtheme to study. The themes were IDH （index of human development）, minimum wage and social security. As an example, a description of the thematic project about the minimum wage in Brazil is presented. The principal results obtained in the study of this theme include a discussion about the potentialities of the theme as a classroom activity in different levels of schooling. As an educational activity, the thematic project demonstrated itself to be greatly relevant, since not only did it provide the learning possibility of mathematics related to the issues studied, but also promoted various discussions regarding the theme, which, in our conception, contributes to the social-critical development of the students. Finally, from the point of view of applied mathematics and mathematics education, the development of a modelling activity from thematic projects showed itself to be a good source of researches.展开更多

A well-developed consciousness profoundly influences a person＇s actions and conduct when solving problems of what is thought, or taught to be, right or wrong Compelling neurological evidence supports the claim that children begin to develop enduring ethical standards at an early age and that these standards are largely based on the experiences of early childhood. Essentially, the innate sense of ethics requires nurturing during infancy before it can be cognitively understood and practiced in maturity. In biological terms, the development of neural networks that regulate emotional growth, and subsequently, the capacity for ethical discrimination, depends on the infant＇s early social environment. Thus, the toddler＇s early epigenetic experiences enhance, or impede, its innate still dormant genetic potential. Importantly, personal character development and ethical discrimination begins long before the child＇s formal educational years. As a consequence, early learning has to discover ways of conserving adaptive thinking which can be applied to the choices that may confront future generations. Early ethics education, including accurate access to scientific, medical, and technological knowledge, is thus critical. Future generations will increasingly require education from a global perspective when making major ethical decisions in areas, such as nuclear technology, disposal of wastes, preservation of biodiversity, global warming, and unregulated human population growth. As long as our culture continues to reflect advances in science and technology, there is an obligation to make science education overlap with crucial periods in the advancement of ethical consciousness. Significantly, when considering the human capacity for excess at times of conflict, it is incumbent on the scientific community to integrate research-based knowledge with wide-ranging learning and problem-solving skills. Bioscience ethics, the established interface bridging applied science and applied bioethics, can assist in this process of integration. To become fully responsible adults, we must share our extraordinary cognitive talents and respect life on earth in all its rich diversity. In biological terms, human uniqueness resides primarily in our brains with its products being co-operation in family and ancestral units, long education, sophisticated language and culture, and importantly, ethical consciousness-all attributes held in trust by knowledge and wisdom for future generations.展开更多

Investigation thoroughly on the effect of traditional Chinese medicine and traditional health care sports for the development of modem community sports is to examine and understand its meaning and value from a higher level, to better inherit and carry forward the excellent traditional culture of China and thus to explore meeting point of traditional Chinese medicine and traditional health sports and modem sports. It also ensures the community to establish a healthy concept, improve the cultural quality, strengthen the moral cultivation, rouse the national spirit, increase life interest and form the modem community culture. In short, by the national education of traditional Chinese medicine and traditional protection movement, there is a unique advantage other cultures are incomparable.展开更多

Social insect nests protect themselves from non-kin intruders through nestmate recognition based on chemical cues. The recognition cues on adult individu- als are from a mixture of genetic and environmental sources, but the ontogeny and use of recognition cues on eggs has not been previously assessed. We studied recognition by workers of eggs that were either nestmates or non-nestmates, and the ontogeny of recognition cues on eggs in the ant Formica fusca, a species with precise egg recognition abilities. Workers were able to dis- criminate among freshly laid eggs with no nest derived cues on them, and the egg surface chemicals varied among nests in these eggs, suggesting that queen derived cues are used in nestmate recognition. The results are discussed in the light of their implica- tions on deceptive social parasite strategies and within colony conflicts展开更多
