Quality is one of the important indexes. Two mainstream theories guide us to realize the industrial sustainable development: mainly the circular economy and sustainable manufacturing are introduced. The basic characteristics of the sustainable manufacturing are introduced, and that quality management is important contents of sustainable development is indicated. Based on circular economy and sustainable manufacture theories, the drawbacks in the existing quality management models are analyzed. The requests that satisfy the big system "environment- society - economy" are summarized to build up a model. A Chinese traditional cultural principle is applied and the relevant contents are sublimated as the platform to set up the model. The new quality management concept models are put forward "T- D- R" three-dimensional structures and "ecological quality loop" model, from which the new quality concepts are formed The paper elaborates the contents and the process of setting up the models. The big quality problems of the system can be handled by the new quality concept and model that are validated in practice.展开更多

Politics is changing to reflect shifts in economics which is simultaneously causing social strife and unrest. Technology has disrupted many business models and with rapid advancements will change the way we live, work, and interact with each other. So much so that this new reality is being termed as the fourth industrial revolution. We are clearly on the edges of the new times but are trying to make sense of it all ironically with a mindset which is anchored in the past. To be future ready, the future has to be forecasted or imagined or even willed by the collective consciousness of humanity. This paper has captured the changes through extensive research and personal insights into the changing paradigms.

The study is based on a sample survey covering 600 youth cohorts in Yanbu and Jeddah in the Kingdom of Saudi Arabia. The study reveals that school-to-work transition is not a smooth one and is influenced by the perception of youth towards employment and its various dimensions along with the ambitions towards career improvement. The 14 indicators framed in the paper reveal that essentiality, confidence to get a job that satisfies the needs, job availability, and qualifications are found to be important determinants of youth's attitude towards work; whereas, willingness to do any job did not get much acclaim. Job selection of youth is determined by location (especially hometown job), sectoral preferences, training options, and work environment.展开更多

The proposed model is based on well-known concepts of Ubiquitous Computing and can enable some degree of contextual perception of the environment. Compared with classical industrial robots, usually preprogrammed for a limited number of operations/actions, the system based on this model can react in uncertain situations and scenarios. The model combines ontology to describe the specific domain of interest and decision-making mechanisms based on Bayesian Networks to enable the work of a single robot without human intervention by learning Behavioral Patterns of other robots in the group. The described model is designed to be expressive enough to provide adequate level of abstractions needed for making timely appropriate actions and respecting the current application.展开更多

However, the global crisis revealed the major weaknesses of the economic model which was implemented. It turned out that the Macedonian economy is very dependent on the performance of only a few sectors and movements on the prices of its most important export and import products, and that the scope of supply and demand for domestic goods and services is small. These lectures from the economic crisis posed by the need to create a new model for country economic development in the future. The application of historical, statistical, analytical and comparative method shows that Macedonia should exercise other holistic approach in the remodeling of their economy. This means that, besides keeping macroeconomic and financial policy in the future the Macedonian government should act more vigorously in the direction of creating new jobs and provide greater social security. The economic model that we propose in this paper recommends it be done by encouraging small and medium enterprises, diversification of production, encouraging domestic investments, developing human capital, improving infrastructure, encouraging exports and harmonization the macroeconomic instruments. The application of this model will result in increasing investments, industrial production and exports, increasing the competitiveness of domestic products, reducing the trade deficit and maintaining the macroeconomic stability. The general conclusion of the paper is that application of the proposed economic model should lead to realization of two most important goals: achieving lasting, sustainable and significantly higher rates of economic growth and reducing the high rate of unemployment in the country.展开更多

What leisure and sport bring to people is bound to be a civilized, healthy, happy, and new life patterns. Throughout the development of sports and leisure history, we can see that in the era of leisure sports agricultural, civilization reflects a more casual game. Strictly speaking, leisure sport is a product of the birth of modern industrial civilization. But today, it has become a recreational sport entirely necessities of life, recreation is the ultimate ownership of human beings, but also one of the best state of human existence, and therefore we have reason to believe that in the near future, leisure Sports will bring a self-liberation and ultimate human freedom.展开更多

As the most important researches of the New Economic Geography, Poter's diamond model generalizes the internal mechanism of clusters, but the model has not given the microcosmic status of the factors of the clusters, therefore, it is significant to go deeper into the diamond model and the dissertation wishes to do some researches deeply.Based on the actuality of research, this paper surveys Porter's diamond model from the Evolutionary Economics, and combines the research of the field with the instance in China, then puts forward the diamond model of twin-screw and implements the model into traditional industrial clusters in Zheiiang province. Detailed explaining is as follows. The main innovations of the dissertation are as follows: (1) having taken the points of biology into economics, and developing the Evolutionary Economics creatively; (2) having proved the diamond model, put forward a twin-screw microcosmic model for the first time, and tried to study the dynamic and solid relationships of each factor in the diamond model, which is the most important innovation of the dissertation.展开更多
