ICT converged smart factory started from German Industry 4.0 has been the driving force for the $4^{th}$ Industrial Revolution and the center of manufacturing innovation for major industrial countries. It will be developed according to industry characteristics of each country. Korea is relatively later than other competing countries in the smart factory area. So, the government is establishing related policy and tendering all sorts of supports for smart factory mainly to the small and medium-sized enterprises to spread over the manufacturing industry. It is necessary for government to categorize among similar manufacturing industry and make them share digitalized production information mutually. It will be more effective method for securing global competitiveness than the uniform support. Also, large companies need to establish cloud based production forecasting system over similar industry and share it with other companies rather than expansion of individual smart factory. Mutual development in the manufacturing industry will be realized when the small and medium-sized enterprises and large companies take part in the cooperating ground of smart factory.

The main purpose of this research is to analyze the changes in investment motivation by year through time series and cross-sectional analysis of the factors and investment decisions of Korean manufacturing companies. According to the investment pattern for Asean from the 1980s to the 19th, the first expansion period was 82 to 86, the average increase in overseas investment for securing foreign raw materials due to the second oil shock, and the second expansion period was a gradual increase in exports to the U.S. in 1987 to 1996. During the first stagnation period, direct investment in Asean stagnated in the aftermath of the 1998-05 Asian crisis, and in the third expansion period, part of the production facilities invested in China were relocated to Asean, increasing Asean's investment to become Korea's largest manufacturing investment in 17. Korea's proportion of investment in Asean surpassed that of mass investment since 10 years ago, and the proportion of investment in manufacturing sector has been transferred from China to Asean, and after 17 years, it has served as an overseas production base connecting China. As such, The main purpose of the research will be to extract the determinant factors and key factors for overseas direct investment and investment patterns in conjunction with global manufacturing companies' production base relocation and investment trends through empirical analysis. This research paper gave basic reference to the motivation and determinant of investment 16 years ago, and analyzed the changes in investment motivation by year and content through empirical analysis, contributing some reasonable purpose to the decision of companies and policy makers interested in overseas direct investment.

Women workers' proportion was 43.6% of total workers, 63.8% of total contractors. 2. A medical examination enforcement of contractors workers was very poor in comparison with that of employees(p<0.001). 3. A 53.8% of total companies have conducted shiftwork system and 2-crew 2-shift(12 hours shift system) ranked first, 56.1%(151 companies). 4. Only 61.3% of total companies conducted more than 90 days as legal standard of a maternity leave and only 2.6% of total companies had a day nursery. In conclusion, many strategies for women workers are needed by companies and government. For example, the raising of understanding about maternity protection, social support insurancing of woman worker and occupational health system improvement for contractors and small size companies.

Inventory management is one of the important business functions for manufacturing companies to determine market responsiveness. Customers' needs are diversifying, and the life cycle of products is decreasing, thus increasing the importance of inventory management. However, for small-scale manufacturing companies, investing in an IT system for inventory management is practically difficult. In this study, we introduce an inventory and warehouse management model that can be applied simply and quickly in small-scale manufacturing companies. Firstly, we introduce the concept of the properties of inventory and provide an analytical methodology based on the age and quantity of the inventory. Secondly, in accordance with the properties of the inventory, we introduce location management rules for warehouse operation. To apply the proposed model, we studied a wallpaper manufacturing company and verified the applicability of the proposed methods in the field. The proposed model can be applied immediately as part of on-site improvement activities by small-scale manufacturing companies, and inventory management activities are expected to reduce bad long-term inventory and further secure storage capacity for warehouses.

Many Korean companies are challenged to reduce logistics cost and meet environmental-friendly logistics. The textile companies in harsh competition are requested to make improvement on their logistics environment to cut down the total cost. However, they have reached the limit on improving the manufacturing process. We believe that the logistics department is the most improvable part at present. Improving logistics will be highly effective to cut down the total cost. In this study, we present Pad Pool System(PPS) as the solution to save their logistics cost. PPS, which means the shared use of Styrofoam pads, will enable the textile companies to cut down their cost and strengthen enterprise competitiveness. Also, PPS will be helpful reducing environmental disruption because the system reuses retrieved Styrofoam pads many times.

Most manufacturing enterprises create CAD data as a result of the product/part design process; however, the CAD data is being utilized only for production activities. Besides the processes directly related to manufacturing such as design and production, the CAD data is an important resource that can be used in variety of services (e.g., catalog production and production manuals) for manufacturing enterprises. This study proposes a software platform that can support a wide range of services for manufacturing companies in an efficient and productive way. The software platform was designed based on the functions identified by requirement analysis. The platform consists of four layers: data model layer to manage relevant data; library layer and common function layer to configure services; and application layer to install and run the software. Finally, this study evaluates the validity of the proposed platform architecture by applying it to the digital catalog system.

The light-weight of the research and development materials is actively carried out by overseas automobile companies and technology development continues in Korea. For the sake of fuel efficiency, the development of lightweight technology by improving the manufacturing method has been very effective. Recently, to maximize the effects of light weight, automotive interior parts have been applied by the micro-cellular injection molding using supercritical fluids and we call the Mucell manufacturing. This technique causes a problem in the quality of the surface of the products, because the shooting cells are revealed as the surface layer of the products by forming micro cells at the center of the products during injection molding. To overcome these phenomenon, we increased the temperature of injection molding using joule heating until critical value. In this study, we have predicted the problem of Mucell injection molding through the finite element analysis as changed the temperature by joule heating. From the result of finite element analysis, we have determined the optimized process and made the injection mold included electric current heating system with Mucell manufacturing analyzed the surface characteristics of the injection product according to changing mold temperature.

Generally, there are laser operating equipments( aligner, stepper) and electronic microscope( SEM, TEM) as a high precision manufacturing and inspection equipment in semiconductor production companies, precision examination and measuring laboratories. Mostly, these equipments are characterized by projection and target part. The relative displacements between projection and target part are dominant roles in vibrational problem in these precision equipments. These relative displacements are determined by the position of incoming vibration and the difference of vibration response in projection and target part. In this study, the allowable vibrational limits are suggested and the vibrational reduction plans are proposed by measurement and analysis of vibration phenomenon in the Clean Room in PDP(plasma display panel) production building. The vibration performance is evaluated by comparison relative displacements between projection and target part before/after the vibration isolation plan.

The purpose of this study is to examine the main characteristics of strategies and fashion styles in fast fashion. Ultimately, this study is aimed to give useful information to develop fast fashion companies in Korean apparel industry. There are several strategies commonly applied in most fast fashion companies. First, they produce a wide range of numerous items. Second, the price is very reasonable. The primary objective of fast fashion is to quickly produce products in a cost efficient manner. Third, fast fashion companies take charge in the whole process from designing and manufacturing to distribution and sales. Forth, while almost all apparel companies invest a large amount in advertisement to promote sales, most fast fashion companies invest in VMD instead. Also, the fashion style of fast fashion were examined. First, casual style dominated a big part in composition of the entire style. Second, they use various kinds of different fabrics. For example, natural fabrics including organic and recycled fabrics, denims, newly invented high-tech fabrics, and decorative fabrics are widely used. Third, fast fashion brands produce fashion product based on the most recent fashion trends. Forth, they pursue high quality design. Retailers' understanding of the target market's wants realizes the consumer to thrive on constant change and the frequent availability of new products. Accordingly, fast fashion is presently taking an important role in fashion although it has a short history compared to the general apparel industry.
