New technology development capability plays a key role in making small- and medium-sized enterprises (SMEs) increase their innovation performance, such as in product or process innovation. To examine the influencing factors of SMEs' new technology development capability, this study empirically analyzes the mediating effects of SMEs' process design capability and product interior design capability on the positive association between their external information network diversity and new technology development capability. This study performs the ordinary least squares regression on a sample of 2,000 South Korean SMEs. Results reveal that SMEs' process design capability fully mediates, and product interior design capability partially mediates the positive association between the external information network diversity and new technology development capability.

The major part of SMES (Superconducting Magnetic Energy Storage) system consist of the superconducting coil, cryostat and current lead, power converter. The 0.7MJ SMES coil was a design and manufacture by using SMES device that we developed a design code. A SMES coil was wound with high winding tension in order to prevent wire motion from Lorentz force. This paper described optimum design for the SMES coil.

For quite a long time various researches and developments of superconducting magnetic energy storage(SMES) device for enhancement of power qualify control of sensitive electric load. This paper describes the design, fabrication and experimental results for the 3MJ SMES magnet made by using the design code of a SMES device that we developed. A computer code was developed to find the parameters of the SMES magnet which has minimum amount of superconductor for the same stored energy, and the 3MJ SMES magnet was designed based upon that. And 3MJ SMES magnet made base of several research result which was ramp up to 1㎄ without quench.

Purpose: The purpose of this study is to support SMEs' introduction of smart factories during the $4^{th}$ Industrial Revolution era. Through this study, we developed the readiness assessment framework for SMEs. This study draws practical implications for improving the readiness of SMEs to introduce smart factories. Methods: Readiness Assessment Framework Design method, Case Studies Analysis Results: This study identified SMEs suitable for smart factories and identified key issues for nonconforming companies. And the diagnostic framework has been determined whether it works in a real-life SME environment. Conclusion: In order to succeed in the smart factory deployment, readiness assessment for SMEs should be performed as necessary. Prior to the introduction of smart factories, quality innovation activities should be carried out according to factory level.

A systematic support system that develops technology support policies for SMEs (Small and Medium sized Enterprises) and solves technical problems faced by SMEs will increase the productivity and competitiveness of SMEs. To this end, it is necessary to identify the types and level of technology required for SMEs, and to find ways to utilize the technologies possessed by government-funded research institutes leading technology development. It is important to develop a new production technology and to establish a cooperation system between SMEs and government- funded research institutes to solve various pending problems.

The 600 kJ calss high-temperature superconducting(HTS) SMES(superconducting magnetic energy storage) system is being developed by Korean Electrotechnology Research Institute(KERI). The system is operated in cryogenic temperature and high vacuum condition. The SMES magnet was cooled by conduction cooling method using a Gifford-McMahon cycle cryocooler. Thus the electric insulation design at cryogenic temperature and high vacuum is a key and an important element. Because it accomplish compact design that is a big advantage of HTS SMES. This paper describes the electric insulation design, fabrication and experimental results for a mini model of conduction cooled HTS SMES.

Technology and knowledge are emerging as core elements of competitiveness for businesses. SMEs lack technology and knowledge, and are also limited in their ability to absorb external knowledge. The government is supporting SMEs' absorption of external knowledge by utilizing retired scientists and engineers, but related research is insufficient. Thus, this study conducted an empirical analysis on the effects of support by retired scientists and engineers at SMEs. Specifically, the study confirmed the effects of company competitiveness and technology development capacities at each stage of technology commercialization. Results of the study confirmed that in an environment where technology competitiveness of SMEs are emphasized, the support of retired scientists and engineers has some effect on the competitiveness of SMEs and their technology development capacity. Therefore, this study suggests important implications for future policy development and execution of related projects.

This paper describes a collaborative work between SEI and KEPCO on the Superconducting Magnetic Energy Storage system (SMES). We have studied two types of magnets. One is the 400kJ class LTS-SMES for testing the power stabilization operated at liquid helium temperature (4.2K) and the other is the 100J class HTS-SMES for confirming the possibility of applying HTS wire to SMES at liquid nitrogen temperature (77k). In this paper, the design of the magnet and the test results are described. Each magnet performed completely at rated operation.

Superconducting Magnetic Energy Storage (SMES) can inject or absorb real and reactive power to or from a power system at a very fast rate on a repetitive basis. These characteristics make the application of SMES ideal for transmission grid control and stability enhancement. The purpose of this paper is to introduce the SMES model and scheme to control the active and reactive power through the power electronic device.

This research aims to identify promising IT items from the perspectives of Korean SMEs and further to development a policy for SMEs in the IT industry. For this purpose, we adopted a bottom-up approach by discovering IT items on high demand by SMEs as their now growth engines and thus used a survey method. We also analyzed the ecosystem characteristics for the items to help policy-makers establish customized strategy to support their growth. We believe that this research is timely when the concept of ecosystem has emerged and the role of SMEs is emphasized in the IT industry. And the research results are expected to produce valuable information to make a policy for promoting IT items for SMEs and ultimately leading to balanced growth of large firms and SMEs.
