This paper presents a production information monitoring system as an infrastructure of CIM system in footwear industry. The system is composed of hardware devices of terminal, communication converter, line controller and software for manufacturing processes. A terminal like a scanner is used for shop floor data input and a line controller is used to link between terminal and server. LAN and RS485 are used for connecting hardware components and deliver their information mutually. In the system, real time production information is acquired from information resources such as group of uppers and soles. The collected production information is delivered to a line controller and analyzed. Server receives information from line controller and machines for production management. Production planning information that is machined in the server is delivered to the shop floor and used for the production management of work in process, and used for improvement of productivity in a footwear production company. The implementation of the developed system shows the effectiveness of the system.

In recently, the influence of client-server systems on organizations and how to estimates the efficiency or productivity of organizations and departments has come to be more concerned by many researchers. Especially, information systems(IS) of the financial institutions are greatly used than any other industries. Therefore, the efficiency of IS departments in financial institutions is relatively important. The overall objectives of this research are to estimate the effects of client-server systems and to evaluate whether the client-serve systems really improve the efficiency of information system. The research method used in this research is DEA(Data Envelopment Analysis) estimation method which based on linear programming is used for the efficiency of managerial organizations and other nonprofit organizations. The results of this research showed that the efficiency of IS department was promoted after implementation of client-server systems.

Many advanced products and services are emerging in the market thanks to data-based technologies such as Internet (IoT), Big Data, and AI. The construction of a system for data processing under the IoT network environment is not simple in configuration, and has a lot of restrictions due to a high cost for constructing a high performance server environment. Therefore, in this paper, we will design a development environment for large data analysis computing platform using open source with low cost and practicality. Therefore, this study intends to implement a big data processing system using Raspberry Pi, an ultra-small PC environment, and open source API. This big data processing system includes building a portable server system, building a web server for web mining, developing Python IDE classes for crawling, and developing R Libraries for NLP and visualization. Through this research, we will develop a web environment that can control real-time data collection and analysis of web media in a mobile environment and present it as a curriculum for non-IT specialists.

This study is to construct ODBC Database based Web, which has a structure of Web server and Database server connected with Database concerning server demand for the purpose of the efficient record, use and management of various document data. Each ASP OLE DB ran be saved and inferred by measuring CLC and ULC. That makes to record, use and management of document data more convenient. For the application of the suggested of the system this study is to put together into 6 categories and generalize the synthetic opinion column of high school student document.

Management of internal Internet servers is increasingly becoming an important task. According to meet this requirement, they use service log analysis tools and network monitoring tools. But these are not enough to produce advanced management information considering contents of Internet services. Therefor we propose a system and let it detect Internet server systems existing in internal network and individuate those systems with providing profile. Internet server profile includes system's basic information, network traffic information, and Internet service usage information.
