This study examines the efficiency of engineering education using DEA(data envelopment analysis) which is often used in the efficiency evaluation of public services. We evaluate 27 mechanical engineering departments according to academy-basis, general basis, and employment-basis considering students' academic level and input costs as input factors. Our empirical results suggest that an evaluation method using DEA can give us useful informations such as benchmarks to improve education specialization where it is desirable, decisions about whether a department should expand its gross input or not, and proper directions about which input factors should be controlled and how much control is needed.

With the development of photovoltaic industry, the cost of photovoltaic power generation has become the significant issue. And the metallization process has decided the cost of original materials and photovoltaic efficiency of the solar cells. Nowadays, double printing process has been introduced instead of one-step printing process for front contact of polycrystalline silicon solar cells, which can effectively improve the photovoltaic conversion efficiency of silicon solar cells. Here, the relative cheap Cu paste has replaced the expensive Ag paste to form Ag/Cu composite front contact of silicon solar cells. The photovoltaic performance and the cost of photovoltaic power generation have been investigated. With the optimization on structure and height of Cu finger layer for Ag/Cu composite double-printed front contact, the silicon solar cells have exhibited a photovoltaic conversion efficiency of 18.41%, which has reduced 3.42 cent per Watt for the cost of photovoltaic power generation.

The significance of intellectual property in the knowledge-based society has been increasing and as a result, the patent customer's demand for a top quality patent administration service has increased as well. Therefore, Korean Intellectual Property Office(KIPO) adopted 6 sigma as a tool for KIPO's innovation to improve the quality of patent administration and enhance customer satisfaction. KIPO's steadfast promotion of 6 sigma resulted in many successful outcomes such as improvement of policy and service process from customer's point view, streamlining the administrative procedures, increased work efficiency, capability enhancement of core personnel, and so on. Since 6 sigma has proved itself to be equipped with features suitable for innovation in public sector, it can be used as an extensible innovation tool to meet the challenges in rapidly changing administration environment and to achieve a competitive edge.

This research aims at conducting a comparative study on the relative efficiency of technologically innovative activities between manufacturing and service industries using data envelopment analysis (DEA). First, as an individual approach, efficiency of technologically innovative activities between manufacturing and service industries is separately evaluated. The results show that efficiency of both industries is similarly low, but patterns of technologically innovative activities differ from each other. Manufacturing industries usually do innovation focusing on various outputs with a single input, whereas service industries tend to do innovation emphasizing on a single output with mixed inputs. Second, as a holistic approach to both industries, efficiency is collectively assessed. The analysis demonstrates that efficiency of service industries is higher than that of manufacturing industries, and there are similar patterns of technologically innovative activities between both manufacturing and service industries. This study provides industrial managers with policy implications based on similarities and differences between manufacturing and service industries.

With the continuous development and application of Internet technology, in recent years, new technologies such as cloud computing, big data, the Internet of Things, and AI are becoming more and more familiar to the general public. The development of a digital society has entered a new period of development. In this paper, we used on the 2018 annual data of 50 listed companies with blockchain concept stocks in China. Using data envelopment analysis (DEA) to study and analyze the input-output efficiency, it can be concluded that the input-output efficiency of 50 listed companies is very different. Inefficient companies are as high as 62%. Most companies have a large room for improvement in input-output efficiency due to uneconomical scale or inefficient technology. In order to better improve the company's input-output efficiency, one must improve the efficiency of resource utilization, optimize the company's research and development costs and the input and management of technical personnel; the second is to increase technological innovation and business innovation.

If Korea Research & Development reinforces integrated control function, indeed would Korea Research & Development's output be increased? Truly, could Korea's competition be ultimately improved with technology innovation and accumulation of knowledge. Can reinforcement of Integrated control that reinforced efficiency of Research & Development's investment effects make Korea Research & Development's investment,itself, be decreased? I try to answer clearly that in a way to reorganize Korea technology Administration's system, introduced Korea Research & Development integrated control system's establishment is what to effect Korea innovation system's direction after answering clearly previous mentioned problems. In this study, to answer these problems view theoretical discussion about Korea innovation system, integrated control system and system dynamics. Set up analytic tools of system dynamics which includes Korea innovation system and integrated control system. Then, draw a general casual loop diagram, which includes established Korea Research & Development's integrated control system, of Korea innovation system's activity. In based these, develop situation model to analyze trend of Korea innovation system and derive a political meaning by analyzing value of Korea innovation system's major inflow, outflow and stock variations according to extent of Korea Research & Development's integrated control in the same model.
