This paper is one of the types of 'sharing economy', a social economic model that borrows and shares things, spaces, and services from the development of the 4th Industrial Revolution. Through sharing of empty space and time in the city, I would like to suggest a way to reduce the closure of small business owners in order to create jobs, which is one of urban problems in the community. We also build a platform that utilizes the free time and space of buildings through space sharing, one of the types of sharing economy, and provides education programs for start-up education, promotion, marketing, and consulting by matching small business owners with building owners. Therefore, in this paper, by sharing the space and time, the landlord and the small business can share the profits of the small business by reducing the business owner's closure and the job creation plan. Coaching urban regeneration was proposed.

The R&D investment of power industry has significant influences on the social welfare as well as national economy. It is necessary to analyze how efficient the R&D investment has been performed. The objective of this study is to verify the efficiency of the R&D investment in the domestic power industry. A formula was introduced to by calculate the appropriate amount of R&D investment of monopolistic industry under the regulations which are determined by the proportion of R&D elasticity and price elasticity. It has resulted that there would be no economy of scale as the sales of electricity increases at the same rate of the increasing cost. The R&D investment in the present electricity industry has been performed inefficiently by showing the negative impact on price-cost margin of the intensity of R&D investment, which is the extent of R&D investment to reinforce economy of scale.

Purpose - During the past twenty years, China has developed rapidly in economy. Meanwhile China's economic development has brought great many problems. Sustainable development is to achieve coordination in the ecological, economic and social aspects. Among them, the environment and resource issues are the most critical issues which affecting sustainable development in China. With China's rapid economic development, China's ecological environment is facing the most serious threat in water pollution, air pollution, solid waste pollution and the destruction of forests and biodiversity, resulting in a significant loss of the national economy. This research aims to examine whether the tragedy of the commons has hindered the sustainable development of China's economy or not. On the other hand, we try to analyze a solution to improve this situation. Research design, data, and methodology - Theoretical background study, finding optimization models, and data analysis. Results - In the case of a clear definition of property rights, the air will have a market price. The market price will coordinate pollutant emissions. Conclusions - The tragedy of commons has hindered the sustainable development. The model of China's Economic development should be changed.

Basic summary of the medical administration : Due to Qing dynasty being the last of the dynastic era, it revealed overall extreme political traits in politics, economy, phenomenon, and cultural aspects. Few emperors of the early Qing dynasty adopted appeasement policy that mitigated ironies to a certain extent and showed growth in various business related fields. Even the medical administration had freshness during that period. United medical administrative system was generally formed, chicken pox was effectively prevented, shamanistic treatment was banned, medical journals were complied by the government, medical relief was more intensely done. However, actions on restoring Ming dynasty and against Qing dynasty as well as the reform power grew against Qing government threatening it. The drastically grown forces from the western region damaged Qing dynasty that the governors had to adopt despotic measures in politics, economy and culture. Social chaos began to arise, economy stagnated and weakened that the medical field also dwindled to the point where it could not be restored to the original point. The era of Qing dynasty was the period that had scientific culture at its fast growing pace, but for Chinese medicine, by contrary, due to autocracy and other factors, was faced with barriers in the medical development.

Recently the construction of high-rise hybrid type building is progressively increased as the social demands. It is significantly important factors such as economy, the safety of structure, and the flexibility of internal space. Therefore new hybrid structural system, using slim flat plate system, is also required to be attained the reduction of story height, the flexibility and efficient use of space. The most suitable structural system is ,with the economy and flexibility, flat plate system in high-rise hybrid type building. But it was focused in the seismic performance for high performance flat plate system in high-rise hybrid type building. Therefore, in the study, to develop the new flat-plate system with high ductile, durable, good performance for the applications. It was evaluated the seismic performance in the critical region of slab-column connection. And then high performance flat plate system, designed by the economy and safety, was developed as a new technique in the application of high-rise hybrid type building.

How to protect the environment without sacrificing the human environment and economy at the level of region is on of the most difficult issues of recent times. The dynamic Interactions between economic activities and environmental pollution control activities determine whether social welfare is increased of decreased by such activities and provides a basis for saying whether they help or hurt the economy. Bureaucratic Approach of Local government has failed, and an Impetus has arisen to develop new tools of analysis, useful for finding policy leverages focused on sustainability. This paper focus on understanding dynamic relationships between regional economic system and environmental system, and presenting possible framework for finding policy leverages in dynamic interaction behaviors. The case, selected in this study, is Nacdong river regions case, which is related many meaningful issues about sustainable development： two big metropolitan government and dwellers have different opinion with regard to construction of large scale Industrial pack, drinking water supply, and environment model consisting of three sectors： regional economy sector, river pollution and drinking water sector, environmental protection and investment policy sector Finally, this paper deal with how to link policy leverage to causal loop structure for the sustainable development of two regions.

The construction industry is now facing a new challenge of green construction. Based on a research question of "what motivates contractors to pursue green construction", the objective of this study is to identify and discuss key characteristics and implications of green construction motivators among major contractors. The Political Economy Approach was adpoted as a main research methodology. The study demonstrated that major contractors show a high level of expectation in the future of green construction and consider economic factors as higher motivators while paying attention to social trends towards green construction. In particular, internal economic motivators were highly considered and the commitment of senior management was viewed as a key motivator.
