This study aims to examine the effects of industrial clustering and manufacturing flexibility on innovation capability and operational performance. This study follow a survey method to collect data pertaining to the phenomena of industrial clustering, manufacturing flexibility, innovation capability, and operational performance by utilizing a single respondent design. A total of 124 Indonesian manufacturing SMEs are taken to test the proposed theoretical model by utilizing covariance-based structural equations modeling approach. It was found that both industrial clustering and manufacturing flexibility was positively associated with operational performance and innovation capability as well. In addition, innovation capability may account for the effects of industrial clustering and manufacturing flexibility on operational performance. This implies that manufacturing SMEs have to reorient their production and operation perspectives, including agglomerate with other similar or related SMEs to develop and utilize their own resources. The SMEs also need to possess some degree of manufacturing flexibility in respond to the uncertain environment and market changes. In addition, the SMEs should put a greater emphasize to use industrial cluster and manufacturing flexibility benefits to generate innovation capability to achieve high performance.

Recently, electric power reliability of our country has been improved. However, there are still remaining problems which are short-duration variations like instantaneous and momentary interruption and voltage sag by nature calamity ; typhoon, lightning, snow, etc. Besides, power quality ; harmonics, caused by using power electronics equipments, become a hot issue Malfunction of controller and stop machinery, and losing the important data are caused by poor power quality at a couple of second. Due to those, UPS, which is made up battery, has being used, but there are several disadvantages ; long charge and discharge time, environmental problem by acid and heavy metal, and short life time. As generally know, micro-SMES is a method to settle those mentioned. However, there need huge system apparatuses in order to verify the effect of system efficiency and stability considering the size of micro-SMES, the sort of converter type, and various conditions ; inner temperature, magnetic field, quench characteristic of micro-SMES, and etc. In this paper, in order to bring the mentioned above to a settlement, a micro-SMES is modeled with characteristics of micro-SMES is interfaced to EMTOC program using Fortran program interface method. We obtained hopeful answers and made the simulation model of micro SMES.

Purpose - Based on the Korea-China FTA as the starting point, this paper makes an empirical analysis of the main influencing factors of the FTA utilization and performance of SMEs. Design/methodology - Taking into account the relationship between the internal and external environmental factors on FTA activities and performance of Korea's SMEs, with PLS-SEM and data obtained by the questionnaire, Smart PLS was applied for the analysis. Findings - The recognition of FTA in SMEs has a significant positive effect on FTA utilization and performance, the international marketing orientation factor only has a significant positive effect on the performance, while the inadequate improvement of non-tariff barriers has a significant negative impact on FTA utilization. In addition, FTA activity has a significant mediation effect on two paths. Originality/value - This paper is of great practical relevance as a tool to enable SMEs to make effective utilization of Korea-China FTA and improve their imports and exports. The paper helps grasp the main factors affecting the utilization and performance of FTA for SMEs, also to establish FTA Business Model and FTA utilization plans for specific industries in the future regarding tariff and non-tariffs compatibility.

The primary objectives of this study is to examine and identify the historical factors that have significantly contributed to the growth/ expansion and prosperity of SMEs in the Republic of Korea and to evaluate and assess the impact of historical factors on the economic progress/ development, innovation, and job creation within SMEs in South Korea. To achieve the purpose of the current study, the present author has investigated the comprehensive literature investigation and figured out a total of four Key historical factors of SMEs for Economic Growth in the Republic of Korea, such as (1) Government Policies, (2) Technological Advancements, (3) Access to Finance, (4) International Trade. In conclusion, this study has undertaken a thorough investigation into the four critical historical factors that have significantly affected the development and achievements of SMEs in the Republic of Korea. By addressing a notable gap in current scholarly work, this study not only adds to the existing pool of knowledge but also provides valuable insights for various stakeholders. Practitioners/ professionals should proactively participate in government support initiatives/ programs and financial aid. SMEs can benefit from monetary incentives and donations/ grants intended to stimulate research and development, creativity, and international trade ventures.

2015년~2021년 혁신인증을 획득한 혁신형 중소기업과 일반 중소기업에 대해 생존기간의 관점에서 비교·분석하여 정책적 시사점을 도출하였다. 업력, 규모(고용인원, 자본 및 부채, 매출액 및 영업이익), 한국표준산업분류 중분류를 이용하여 혁신형 중소기업과 유사한 일반 중소기업을 선별하였으며, 생존기간은 휴·폐업 및 부도에 준하는 연체를 사건으로 정의하여 산출하였다. 생존분석 결과 혁신형 중소기업은 일반 중소기업 대비 휴·폐업 및 연체 발생 위험이 9.8% 감소하는 것으로 나타나, 혁신형 중소기업의 생존기간이 유의하게 길다는 결론을 도출하였다. 그 외 중소기업의 업력과 규모(고용인원, 자본)는 생존기간에 정(+)의 영향을, 부채는 부(-)의 영향을 미치는 것으로 나타났다. 따라서 혁신역량과 미래성장성 중심의 혁신인증 제도는 생존기간의 관점에서 유의한 지표이며, 혁신인증 제도의 혜택 및 지원정책이 중소기업의 실질적 성장과 생존을 위해서는 업력 및 업종을 반영하여 보다 체계적이고 정교화 될 필요가 있다는 결론을 도출하였다.

This paper describes the design, code of a $\mu$SMES device that we developed. The 0.7MJ $\mu$SMES coil was wound with high winding tension of about 14kbf/$mm^{2}$ in order to prevent wire motion from Lorentz force. This coil was charged up to a current of 1820A with a ramping rate of about 10A/s, where a quench occurred. This quench current is sbout 82% fo the coil critical current.
