SCADA (Supervisory Control and Data Acquisition) System was first introduced to the Seoul Electricity Authority, which manages the transportation part among the three business fields that produce, transport and supply electric power in Korea. Has been using the data link with 1200 bps and 9600 bps in 5 protocols such as HARRIS 6000, BSC, HDLC, L & N and Toshiba by configuring 3 layers of EMS, SCADA and RTU computer equipments in 1: N radial form. This paper presents the OSI standard network packet flow, analyzing DataLink and Network Layer, and presents a KEPCO SCADA network model composed of X.25 high - speed communication network using 3 layers of network. We proposed a future SCADA communication structure that improved the current SCADA communication structure, defined the SCADA DB structure, introduced the concept of the remote SCADA gateway to the SCADA functional structure, applied the standard communication protocol, Multiplexing of surveillance and control in other local facilities and ensuring communication openness

This study analyzed the effect of human resource management on the performance of franchise restaurant workers. First, employment management of franchisees did not have statistically significant effect on business performance. Second, evaluation management (p <.05, β= 1.887) showed a significant effect on job improvement, but did not affect financial performance significantly. Third, career management (p <.05, β= 1.715) was found to have an impact on financial performance, but it did not significantly affect job performance. Fourth, there was a somewhat higher correlation between job improvement and job management (.441), job improvement and evaluation management (.476), p <.01, and financial performance and employment management (.375) (.356), and financial performance and career management (.371) were found to be correlated with p <.05 significance level. This study analyzes the effect of human resources management on the performance of franchise restaurant workers, and finds out the importance of characteristics of factors such as recruitment management, career management, and evaluation management. Research has significance.

This study The study analyzed the effect of the advertisement method of admission at Korea Polytechnic University on the competition rate for entrance to university. A total of 66 questionnaires were analyzed among freshmen and undergraduates at Korea Polytechnic University in Seoul. The first study revealed that the ground promotion (p <.01, β=. 363) had an effect on the competition rate, with the ground promotion having a statistical effect on the competition rate and therefore having a significant competitive edge. Second, it was analyzed that the ground promotion and registration rates were correlated to the p×.01 level with the. 297 level of media promotion and registration rates. Third, although the motivation for knowing the junior high school records and the Korean Polytechnic University did not significantly affect the registration rates, it was found that there were group differences because the admission patterns were higher than usual on time. This study analyzes the effect of the admission promotion method on the competition rate of the university, identifying the importance of ground advertisement, media promotion to the competition rate and registration rate, and identifying the effectiveness of characteristic factors.
