China’s environmental scientific research and technology development:review and envisage

The topic was concentrated on environmental technology development in China within the context of China's economic acceleration and reform. Firstly, cleaner technology should be adopted where possible in industrial production; secondly, eco agricultural technological system, especially biological technology, should be developed in agricultural production; thirdly, end of pipe solution should focus on waste utilization or recycling technology where appropriate clean technology does not exist; lastly but not the least, existing technologies to minimize eco environmental deterioration such as soil erosion, salinization, desertification and deforestation should also be extended and developed. The mentioned ways of environmental technology development can only be realized on the condition that a resource conservation based production system and life style could be established and appropriate policy secured.

An Entire View on Research Trends in the Technology Evolution of Mobile Telecommunications

＂Without an appropriate research setting, a study cannot be qualified as a reasonable piece＂, this notion is manifested in the methodological polices. In this research, we attempt to examine previous studies within the scope of technology evolution and market perception in telecommunication industry through extracting research structures, methodologies, corresponding variables, and processing methods. A general process of social scientific research is adopted to analyze eighty-four selected papers; and simultaneously, the framework for doing this analysis is established, as well. In this manner, we inspect the subjects and the issues in these papers according to product types, academic domains, and divisions of technological evolution （from 1G to 4G）. Then, their research designs are anatomized into the key dimensions of general research conventions. This research eventually provides an entire picture of a research scenario for mobile telecommunication industry; and apparently, this framewbrk can help scholars to establish specific tendencies for academic scenarios in future research plans. Also, we propose the main streams and emerging issues can be expected to engage in the future within both theacademic and the operational fields.

Technology-Transfer Through International Network Formation： Revisiting the Role of Cultural Variation

This paper studies the factors affecting the technology-transfer within international research and development （R＆D） networks. Specifically, this study examines the characteristics of ties, actors, and international network configuration to assess finn＇s accessibility to unique technologies. This study was conducted by research analysis in the aerospace industry. The total sample size used in this study is 125 cases of international R＆D consortiums from January 1980 to December 2000. The result of this study supports the effects of ＂strength of tie＂ and ＂characteristic of actors＂ on the technology transfer explained by network theory. It also demonstrates that the international network structure that would facilitate the technology transfer is shaped by dual type of tie; the apparent type of tie is general, usual, and functional tie, and the hidden one is the national culture.

Predictive Mathematical and Statistical Modeling of the Dynamic Poverty Problem in Burundi: Case of an Innovative Economic Optimization System

The mathematical and statistical modeling of the problem of poverty is a major challenge given Burundi’s economic development. Innovative economic optimization systems are widely needed to face the problem of the dynamic of the poverty in Burundi. The Burundian economy shows an inflation rate of -1.5% in 2018 for the Gross Domestic Product growth real rate of 2.8% in 2016. In this research, the aim is to find a model that contributes to solving the problem of poverty in Burundi. The results of this research fill the knowledge gap in the modeling and optimization of the Burundian economic system. The aim of this model is to solve an optimization problem combining the variables of production, consumption, budget, human resources and available raw materials. Scientific modeling and optimal solving of the poverty problem show the tools for measuring poverty rate and determining various countries’ poverty levels when considering advanced knowledge. In addition, investigating the aspects of poverty will properly orient development aid to developing countries and thus, achieve their objectives of growth and the fight against poverty. This paper provides a new and innovative framework for global scientific research regarding the multiple facets of this problem. An estimate of the poverty rate allows good progress with the theory and optimization methods in measuring the poverty rate and achieving sustainable development goals. By comparing the annual food production and the required annual consumption, there is an imbalance between different types of food. Proteins, minerals and vitamins produced in Burundi are sufficient when considering their consumption as required by the entire Burundian population. This positive contribution for the latter comes from the fact that some cows, goats, fishes, ···, slaughtered in Burundi come from neighboring countries. Real production remains in deficit. The lipids, acids, calcium, fibers and carbohydrates produced in Burundi are insufficient for consumption. This negative contribution proves a Burundian food deficit. It is a decision-making indicator for the design and updating of agricultural policy and implementation programs as well as projects. Investment and economic growth are only possible when food security is mastered. The capital allocated to food investment must be revised upwards. Demographic control is also a relevant indicator to push forward Burundi among the emerging countries in 2040. Meanwhile, better understanding of the determinants of poverty by taking cultural and organizational aspects into account guides managers for poverty reduction projects and programs.

Investigation on the Effect of the Cultivation of Consumers'Scientific and Technological Concept on the Sales of Skin Care Products

The number of skin care products developed scientifically and technologically is increasing in the market now.Whether it is a gimmick or a real desire to make a good product,companies are actively promoting the development and growth of the technological skin care market.The analysis of our market survey indicates that companies and consumers generally show a trend of mutual progress along with the market growth of technological skincare.Companies and consumers alternately play a leading role in different stages of progress.In this survey study,consumers were divided into four types:minimalist consumers,trendy consumers,ingredient-based consumers,and technological consumers.A series of comparative analyses for these four groups showed that consumers have the trend to instinctively develop from minimalist to technological consumer.Along with the increase of skin care knowledges,consumers can more trust and be more willing to buy the technology-based skin care products.For those ones who has no experiences with the technology-based skin care products,after gaining skincare knowledges,they are also willing to try.This is a good signal for companies.While helping with consumers being more knowledgeable in skincare,companies can lead consumers to learn about their researches and products development,which will benefit the market acceptance of the products.Users can also benefit from gaining more relevant knowledges.With these knowledges,consumers can be clearer about their own needs,more rational on skincare purchasing,and they can select the correct skincare.
