It analyzes the thinking mode of interaction design, describes how to make the product provide better experience for the user, from the perspective of the four elements of people, activity, context and technology, and shows how to combine interaction thinking for product derivation through the cases. Good products in addition to the realization of the function also need to meet the needs of the user experience. Product derived can get new methods and ideas from the interaction design of systematic thinking, so that products can provide better service for users in the digital era.展开更多

A linear map φ on N（n,F） is said to be a product zero derivation if {φ（x）,y] ＋ [x, φ（y）] = 0 whenever {x, y} = 0,x,y ∈ N（n,F）. In this paper, we prove that a linear map on N（n, F） is a product zero derivation if and only if φ is a sum of an inner derivation, a diagonal derivation, an extremal product zero derivation, a central product zero derivation and a scalar multiplication map on N（n, F）.展开更多

In this article, we prove that generalized derivations, quasiderivations, and product zero derivations of P coincide, and any generalized derivation of P is a sum of an inner derivation, a central quasiderivation, and a scalar multiplication map of P. We also show that any commuting automorphism of P is a central automorphism, and any commuting derivation of P is a central derivation.展开更多

This species is protected in Democratic Republic of Congo (DRC) and worldwide, unfortunately it is threatened by numerous human actions. The purpose of this study was to determine the profiles of actors using pangolins, the reasons for pangolin exploitation and its products and their use within the local community in and surrounding the reserve. We carried out surveys in the households of hunters, farmers and people practicing other professions in 12 villages, located within the Tayna Nature Reserve (RNT) and surroundings areas. Two interview techniques were used: the individual interview and the participatory diagnostic technique. During one month of data collection, 175 respondents were interviewed. Respondents had diverse profiles according to sex, age, education level and ethnicity. Men were more represented as actors in pangolin exploitation (71.70%) than women (28.30%);the most represented age interval was 20 - 30 years. The education level is distinct amongst respondents: illiterate (37%), primary school (32.4%) and graduate from university (2.9%). An average number of respondents are motivated to consume pangolin as meat obtained by hunting at 50%. The main reason for its consumption is preference (44%) and habit (33%). The scales are pangolin derivatives most recognized by local people and widely used in the pharmacopoeia. Consequently, pangolin protection needs some rigorous measures to reinforce the current law implementation.展开更多
