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.

Domestic SMEs play a key role in production and employment, accounting for 98.9% of total enterprises, 74.4% of employment, 50.8% of production, and 49.0% of value added (as of 2016). However, they are faced with difficulties of survival because of continuous decrease in profitability, shortage of funds and manpower, insufficient accumulation of technology, minimum wage increase, and 52-hour workweek. In order for SMEs to continue to develop in such a difficult environment, we must constantly innovate our organization by making full use of our knowledge, information, experience and ability. To do this, CEO (management) leadership is very important to ensure that the best people are focused on the organizational innovation and management performance without moving the company. In this study, we wanted to establish empirically how the newly emerging compassionate rationalism leadership of SMEs business managers affected the innovation activities and management performance of companies. Research has shown that management’s compassionate rationalism leadership has a positive and significant causal relationship with the innovation activities and management performance of the enterprise. Therefore, SMEs managers need to learn the bottom eight strategic factors of compassionate rationalism leadership and use them strategically to make efforts to create positive emotions for the organization so that members can be immersed in innovative activities and management performance creation.

The population of domestic companion animals is estimated to be about 10 million now. In recent years, the domestic pet market has been launching a wide range of products and services for high quality, smart and well-being. As a result, the market size will increase from 900 billion won in 2012 to 2.3 trillion won in 2016, which has more than doubled in five years. The industry expects to reach 6 trillion won by 2020, expecting 3 trillion won this year. In particular, domestic dogs and cats market is estimated at 275.5 billion won, accounting for 19% of the domestic animal market and 1.425 billion won for the world market. However, despite the growing market for companion animals products, unfortunately the import dependence on related industrial goods is still high and the quality of service is very low. Unlike Europe and the United States, 90% of companion animals are housed in apartments, often causing problems in the health and safety of companions and companions. The purpose of this study is to develop a smart house for companion animals with environmental friendliness and AI function that can be won in competition with products of developed countries. The results of this study are expected to contribute to the creation of a new value - added base for the related industries through the strengthening of the competitiveness of the related SMEs and further the effect of employment increase and import substitution.

With the recent development of manufacturing technology and the diversification of consumer needs, not only the process and quality control of production have become more complicated but also the kinds of information that manufacturing facilities provide the user about process have been diversified. Therefore the importance of big data analysis also has been raised. However, most small and medium enterprises (SMEs) lack the systematic infrastructure of big data management and analysis. In particular, due to the nature of domestic manufacturing companies that rely on foreign manufacturers for most of their manufacturing facilities, the need for their own data analysis and manufacturing support applications is increasing and research has been conducted in Korea. This study proposes integrated analysis platform for process and quality analysis, considering manufacturing big data database (DB) and data characteristics. The platform is implemented in two versions, Web and C/S, to enhance accessibility which perform template based quality analysis and real-time monitoring. The user can upload data from their local PC or DB and run analysis by combining single analysis module in template in a way they want since the platform is not optimized for a particular manufacturing process. Also Java and R are used as the development language for ease of system supplementation. It is expected that the platform will be available at a low price and evolve the ability of quality analysis in SMEs.

To obtain basic data on bioaerosols in the indoor environments of houses located adjacent to Gwangyang Iron Works, the concentration and diversity of indoor air molds were comparatively investigated in 33 houses in September of 2016 and 2017, respectively. In areas both adjacent to and nonadjacent to Gwangyang Iron Works, house temperature and humidity ranged from 24~28oC and 47~57%, respectively. Airborne mold concentration was higher in the houses located nonadjacent than in the ones adjacent to the iron works. Interestingly, the level of airborne mold concentration exceeded 500 CFU/m3 in all houses nonadjacent to the iron works. A total of 12 mold species including five pathogenic species were indentified from the investigation. Among the five pathogenic species, the causal agents of otomycosis, Alternaria alternata, Aspergillus fumigatus, and A. niger were present. Overall, Cladosporium cladosporioides was the dominant species. This is the first report on the concentration and diversity of airborne mold in houses located adjacent and nonadjacent to Gwangyang bay industrial complex in Korea.

Each municipality is promoting signboard improvement projects, but the effectiveness is not great. The main reason for this is that when the signboard is manufactured the location of the shop is only dependent on the visual aspiration effect and it is not harmonized with the building by applying uniform design. The signboard are installed almost everywhere in the city, such as residential, natural and commercial environments. And the signboard provides various services such as traffic information and life safety to customers. Also, by applying design and functional elements, we can enhance the competitiveness of companies and improve the urban environment by enhancing the mutual connection effect of customers and space. The purpose of this study is to investigate the effect of design elements and functional elements of the signboard on customer preference. In other words, we conducted surveys and analyzes of 152 specialists and non-experts (customers, self-employed). As a result of the study, the following conclusions were drawn. First, the functions and design elements of signboards are important factors that have a positive effect on customer preference. Second, the function of the signboard has a positive(+) influence on the customer preference, and the information providing function and the corporate image side function directly affect the customer preference. Third, color elements have a positive(+) meaningful effect on customer preference. Especially, similar color sign affects customer preference positively. Fourth, the signboard design component has a positive(+) significant effect on customer preference. In particular, typefaces have a positive effect on customer preference.
