[Method] The research was made by comparison, according to the development impetus. [Result] The results show that foreign agricultural informatization is mainly divided into three categories： the first category is the government leading; the second category is the industry self-help; the third category is typical demonstration. Since the reform and opening, Chinese agricultural informatization has made considerable achievements. [Conclusion] The agricultural informatization is significant to promote the update of the traditional agriculture, and it is also essential to Chinese agricultural sustainability.展开更多

Adopting the contrastive analysis to introduce briefly the long-term care insurance system in German, Japan and America for our learning. Therefore, China＇s long-term care insurance system could not totally indiscriminately imitate the mandatory long-term care insurance system in German and Japan, it also could not copy the business model of nursing insurance system in America. The conclusion is that long-term care insurance system in China should use the experience of developed countries based on the basic national conditions, doing some relative works, such as establishing policies and regulations, strengthening personnel training, and improving the market specification.展开更多

Original parcelling, homestead composition and functional layouts have stopped being useful for current village inhabitants. The Czech Republic is an example of an area where this problem has appeared. According to the Czech Statistical Office, the number of inhabitants working in agriculture is now only 1%. Therefore, we need to concentrate on the village historic centre： the possibilities of restructuring and the definition of its potential and possibilities for new development. The internal resources of the village mentioned in this paper refer to the buildings, structures and land of the village centre core. The case studies worked out by the students of architecture in the Faculty of Civil Engineering of Czech Technical University in Prague from the 1990s were used for the research. Comparing designs can define these basic approaches to the new historic centre＇s use： a spatial solution--urban （non-invasive and invasive） and architectonical （reconstruction, traditional form with modern detail or completely modern design） and a functional solution. The research shown in the original historic village core offers enough opportunities for new usages and non-agricultural functions which are suitable for this area.展开更多

We find that the production cross section is larger than that of the process γγ→ W＋ H-H in the minimal supersymmetric standard model. With reasonable values of the parameters in the TC2 model, the cross section can reach the level of a few fb. Furthermore, the flavor-changing （FC） decay mode ∏t^0 → te^- is the best channel to detect the neutral top-pion due to the clean SM background. With a large number of events and the clean background, the neutral top-pion should be observable at future linear colliders operating in γγ mode at the TeV energy scale.展开更多
