The technological advances such as communication, sensor, and artificial intelligence lead smart factory construction. Smart factory aims at efficient process control by utilizing data from the existing automation process and intelligence technology such as machine learning. As a result of constructing smart factory, productivity increases, but costs increase. Therefore, small companies try to make a step-by-step transition from existing process to smart factory. In this paper, we have proposed a remote control system that support data collection, monitoring, and control for manufacturing equipment to support the construction of CNC cutting machine based small-scale smart factory. We have proposed the structure and design of the proposed system and efficient sensing data transmission scheme. To check the feasibility, the system was implemented for CNC cutting machine and functionality verification was performed. For performance evaluation, the web page access time was measured. The results means that the implemented system is available level.

Coal Gasification Technology is one of the best alternatives among clean fossil fuel utilization. Major technology holding companies are devoting their efforts to develop more advanced technology to dominate the market in advance because of its importance on the applications such as IGCC, CTL, coal to SNG, various chemicals and so on. Japan and China, as well as America and European countries, have developed couple of thousands ton/day-class coal gasification technology. However, our gasification technology remains in the development stage with couple of ton/day-class pilot plant. So, we should be interested in developing this technology considering that we are heavily dependent of coal energy. In this paper, we summarized the trend and status of coal gasification technology development and commercial deployment of major technology holding companies mainly from the presentation materials of 'Gasification Technology Conference 2010', which is the biggest place of information exchange for recent coal gasification technology.

Construction is a typical labor-dependent industry. However, problems related to wage payment, which directly affects the livelihood of workers, have caused other problems in maintaining skilled workers, such as increasing the turnover rate of skilled workers, resulting in a shortage of skilled workers. Against this backdrop, this study was conducted to develop measures to improve the conventional wage payment systems in order to prevent skilled workers from leaving their jobs and to maintain them as workers. It is necessary to make the registration of non-registered small-sized construction companies in Korea mandatory, and to introduce means by which construction companies that hire workers through non-registered agents can be penalized. In addition, the project bank account (PBA) system used in the domestic banking sector can be benchmarked in operating payment systems, an approach that is expected to effectively prevent delayed wage payments in the construction industry.

The domestic construction market started to expand steadily since 1970s. The building market which utilizes a sandwich panel with advantages of economical construction expenses and convenient construction has grown rapidly in recent years. However, the companies which specialize in constructing sandwich panels are relatively small or medium size, compared with other construction companies. As a result, studies on the improvement of productivity have not been conducted sufficiently. In this study, the construction sites of sandwich panel are investigated, and the work processes by each team are analyzed. Additionally, the productivity and the construction cost of each construction team are analyzed by constructing a model using the Web-Cyclone. It is expected that the results of this study can be applied to estimate the productivity and the construction cost of a sandwich panel construction that is appropriate for the on-site characteristics of small and medium sized construction companies in Korea. Also, similar processes can be simulated based on the modeling constructed in this study.

As software industry is rapidly evolving, IT business enterprises have been meeting with cutthroat competition in developing software. As software reusability, time to market, and maintainability are considered as a competitive edge, software component techniques have lately attracted considerable attention. Currently, although there are some supporting tools for developing software components, they do not have tight connections among component developing processes such as component identification, component modeling, detailed design, code generation, deployment, and testing. And it is restrictive for users to construct various scales of components on component platform architecture. In this paper, we provide an implementation and a design of a supporting tool for constructing platform-independent software components, which covers all development lifecycles of components. In the phase of component modeling, platform independent, conceptual components are identified from domain model information in the view of system partitioning. Detailed design and implementation of a component are performed on the J2EE platform architecture. And the changes on the design model and source codes are consistently managed by using round-trip techniques.

This study aims to analyze an evolutionary path and the dynamics of the Seoul Digital Industrial Complex in Korea based on the analysis of cluster life cycles. From the mid 1960s to the late 1990s, the life cycles and their characteristics of the Seoul Digital Industrial Complex (Guro Industrial Park) are examined as emergence-growth-sustainment-decline focused on the number of firms and employees. After the late 1990s, the number of firms and employees increases rapidly and the active actors of the growth and restructuring are transformed to the technology-intensive SMEs and knowledge-based service firms. Knowledge industry centers (apartment-type factories) help evolve into the life cycle of transformation as knowledge-based clusters after the mid 2000s.

This study aims to investigate the appearance of Gyeongridangil and its related commercial streets, which seemingly serve as a place brand. Internet trend data, locational conditions, and commercial compositions were analyzed to determine the characteristics of their formation. Result showed that, as the commercial streets developed because of social network services, the street names tended to be considered as place images. In terms of locational conditions, they chose rather remote places, risking the disadvantages for their own spatial style. Interpreted within the framework of place branding, these streets seemed to identify themselves with a unique streetscape using spatial restraints as an advantage. They positioned in a niche area to avoid conflict with other commercial types and attract consumers with the image of "suppliers of trendy lifestyle", thus successfully becoming a place brand.

As the industrial complexes that led the national economic growth of Korea become older, it is necessary to prepare countermeasures to improve the competitiveness of these industrial complexes. The purpose of this study is to analyze the determinants of the competitiveness of old industrial complexes in Korea. It was found that the characteristics of the industrial structures, new companies, the working and production environments, and the regions in which these complexes exist all affect their competitiveness, but the effects differ according to the size of the complex. In particular, for large-scale complexes, the central government should play a role in their restructuring to improve their competitiveness. On the other hand, local governments' management of new companies is more important for small-scale old industrial complexes. These results provide implications with regard to the effective management of old industrial complexes.
