This article looks at the thought of Oh Jae-soon's seonggong sasangin Jeongjo period while focusing on his Seonggongdo and Seonggong doseol. his thought will be explained as seen below. First, he gave more emphasis on seonggong, not seonghak, which is a concept abbreviated from Seonginjihak.He actually gave more importance to practice than to scholarly work. Therefore, the essential concepts provided in his work are most related with drills and practices. Second, he focuses on dotong(characters). Looking at Yosunwoosangjeonsimhakdo, he presents dotong ((Yo-Sun-Woo)-Kongtzu-Chengtsu-Jasa-Mengtsu-Chungtzu), while presenting himself to such a scholarly inheritance. Third, he intended to provide his interpretation based on his consistent thought. He actually classified and analyzed all the characters and classics based on the principles of knowledge, practice, self-esteem, bitter words, diligence. In addition, all things are classified with these five items as shown above. Fourth, he analyzed classics and presented his ideas in simple terms and concepts. Fifth, he deals with the seven Chinese Classics and particularly he emphasizes Shizing and Shujing. He did not mention Chunqiu (the Spring and Autumn Annals) and Liji (The classic of Rites),both of which he did not consider as adequate. Sixth, Sunam's thought was inherited to Ganjae Jeonwoo's soonamhakgyeol.

It is common to optimize the propulsion control system through a so-called tuning process that modifies the parameter values of the propulsion control software during a ship commissioning. However, during this process, if the error of the initial setting value is large, the tuning time may take too long, or the propulsion equipment can be seriously damaged. Therefore, we conducted research on the design of a propulsion controller that applied a Processor lever controller even for inexperienced people with relatively little experience in tuning propulsion control software to be able to reduce the tuning time while protecting the propulsion system. Through simulation, by comparing the execution result of propulsion control lever commands through the PI controller without applying the Processor lever controller. We analyzed the improvement of the Overshoot and propulsion performance. The simulation results showed that the safety of the propulsion system increased because Overshoot of approximately 9.74%, which occurred when the Processor lever function was not applied.

ECS is a control device so that the warship can perform the mission stably by controlling and monitoring the entire propulsion system. As the recent provisions of the warship, it's propelling system is complicated than past, as the demand performance and mission of the warships are diverse. In accordance with the complicated propulsion system configuration, the demand for automatic control function of the ECS is increasing for convenient and stable propulsion system control for convenient and stable. As a result, verification of ECS stability and reliability is required. In this paper, we develop an interlocking signal simulator for verifying ECS control logic and communication protocol for warship with CODLOG propulsion systems. The simulator developed was implemented to simulate a signal of gas turbine, propulsion motors, diesel generator and 11 kinds of auxiliary equipment. The reliability of ECS was verified through the ECS communication program and the I/O signal static test with the simulator.
