As the 4th industrial revolution emerges, the implementation of smart factories are essential in the manufacturing industry. However, 80% of small and medium-sized enterprises that have introduced smart factories remain at the basic level. In addition, in root industries such as injection molding, PLC and HMI software are used to implement functions that simply show operation data aggregated by facilities in real time. This has limitations for managers to make decisions related to product production other than viewing data. This study presents a method for upgrading the level of smart factories to suit the reality of small and medium-sized enterprises. By monitoring the data collected from the facility, it is possible to determine whether there is an abnormal situation by proposing an appropriate algorithm for meaningful decision-making, and an alarm sounds when the process is out of control. In this study, the function of HMI has been expanded to check the failure frequency rate, facility time operation rate, average time between failures, and average time between failures based on facility operation signals. For the injection molding industry, an HMI prototype including the extended function proposed in this study was implemented. This is expected to provide a foundation for SMEs that do not have sufficient IT capabilities to advance to the middle level of smart factories without making large investments.

This study is to examine the remained basis and the locational characteristics of manufacturing in Chonnam region. First, the locational characteristics of manufacturing in the peripheral region examined through theoretical discussions about manufacturing location. And the locational characteristics of the small and medium firms and large firms be studied as to understand the precedent characteristics of Chonnam region. Chonnam region have the precedent characteristics that the regional capital is not accumulated as Japen exploit agricultural products at a colonial period. And SOC, industry and technology are not developed as geographically Chonnam lesion turn aside the economics axis of Korea-Japen-America within a period of industrialization. Manufacturing firms have beer make up the traditional indigenous firms which base on local market, agriculture and marine products in Chonnam lesion. The characteristics of these firms mainly are food & drink, nonmetal industry that is composed of the small and medium sized firms. The industrial structure is changing to machinery, chemistry, electronics industry from food & drink, nonmetal industry. But these industry is making the simple products. In Chonnam region, these change of industrial structure was expanding to the inland or coast region from the neighhoring region of Kwangju metropolitan. The blanch factories of large enterprises that located in Chonnam region are not connected with small and medium sized firms. The small and medium sized firms are not developed. Because these large enterprises are the iron and steel industry or chemistry industry. So the large-manufacturing firms have characteristics of the capital intensive industry, and make up the monopolistic industrial space of fordist blanch factories.

This study is an empirical research to find out the effect on the management performance of hidden champions of food manufacturing companies when using blue ocean strategy for new product development. In order to achieve the purpose of this study, we conducted a questionnaire survey on hidden champions in the domestic food manufacturing industry and proceeded empirical analysis. When small and medium-sized enterprises in food manufacturing industries develop a new product, searching for non-customer, rebuilding the market boundary, and linking the external networks have a significant impact on their management performance. However, the fair procedure did not have a significant effect on the management performance. In terms of relative influence, rebuilding the market boundary was most affecting, followed by searching for non-customer and linking the external networks. On the other hand, this study implicated the management performance of hidden champions of food manufacturing industries when new products is developed by using the blue ocean strategy. Obtained results are as follows. If small and medium-sized enterprises of food manufacturing industries develop new products, it will be able to improve the management performance by utilizing strategies such as searching for non-customer, rebuilding the market boundary, and linking the external networks. In particular, the rebuilding the market boundary among the blue ocean strategies has a relatively high impact on management performance.

Recently, automobile manufacturing companies, which are major customers of them, are requiring IATF 16949 (ISO/TS 16949) certification as a mandatory requirement to secure product quality. In particular, IATF 16949 : 2016, revised in October 2016, was reinforced product traceability requirements for production information management by lot in the production process. Therefore, small and medium-sized precision parts processing companies in the automobile industry are very difficult to survive due to quality and price competition for customers satisfaction. MES (Manufacturing Execution System) is required to solve this problem. However, small and medium sized precision parts processing enterprises are reluctant to introduce the MES which is not suitable for the manufacturing environment of them such as high cost and low utilization. Even if the system is introduced, it is difficult to operate and maintain the system because the lack of computer manpower. In this paper, we propose a method for building a lot tracking system for small and medium precision parts processing companies by reviewing relevant literature and analyzing cases. In addition, by managing the production history for each lot of the final product in the system, we will grasp the effect of reducing the quality failure cost obtained by minimizing the range of defect selection.

This study investigated the method of continuous improvement of small-medium company production processes through POSCO's QSS(Quick Six Sigma) activities. QSS is a field operation technique that encompasses the advantages of Six Sigma, TPS(Toyota Production System), TQM (Total Quality Management), and IE(Industrial Engineering). Through this, POSCO not only encourages activities centered on related small and medium-sized partners, etc., but is also expected to contribute to the continuous improvement of the company's own production process through QSS activities. In this study, rather than unconditionally carrying out activities according to the needs of large companies, the research is to help the continuous improvement of the actual production process of small and medium-sized enterprises by effectively applying and spreading QSS activities in consideration of the characteristics and environment of the company. For this purpose, empirical research is conducted on the process improvement activities and QSS activities of company Y, which has less than 100 assembly and production quality and inspection processes among SMEs. The changes in the production process improvement of SMEs through the application of the final QSS were investigated through empirical studies.

The purpose of this study is to explore and empirically analyze the factors affecting the financial performance of Korean small- and medium-sized manufacturing companies, which are relatively insufficiently researched, in terms of human resource management (HRM). In particular, this study intends to examine the human resource management activities focusing on the individual influences of workers' attitudes on systems and policies as well as jobs and organizations. This study reviews previous research and discussions on the human resource management system, as well as the organization and job-related attitudes and financial performance of workers, for the formulation of two hypotheses. Among the HCCP data, the hypothesis was verified through reliability and correlation analysis and stepwise multiple regression analysis for small- and medium-sized manufacturing enterprises. The results show, firstly, that human resource systems and systems have the same effect, but there were differences in the degree of impact. Secondly, job satisfaction has a statistically significant influence on financial performance. Lastly, all worker/employee attitude determinants are statistically significant for both job satisfaction and organizational commitment. HRM, previously relatively overlooked, provided theoretical and practical implications by demonstrating the direct impact on financial performance and the impact of individual human resource management systems and policies.
