This paper is the research on the relationship between Lee Kyujoon(李圭晙)'s Shimqi(心氣) Philosophy and medical theory of Buyang(扶陽). Lee Kyujoon is the philosopher and medical doctor in the late Chosun Dynasty. His philosophical hypothesis is that the cosmos constitutes of the only entity, Qi(氣) and Medically, human body is also made of the only one entity, or Qi. The Qi of the body comes from Shim (心:heart). So, Encouraging the Qi(扶陽) of heart is the most critical in maintaining life. He is favorably used to prescribe the medications full of the herbs boosting the ShimYang(心陽) of body. In conclusion, his Shimqi(心氣) Philosophy and Buyang(扶陽) theory is the twins of one Shimqi(心氣) monism.

It is definitely important to measure thrust during ground test when developing air-breathing engine, and in case of air-breathing engine, gross thrust should be calculated considering not only the measured thrust but also the force induced by the air flow of engine intake. Also, side thrust like yaw and pitch should be measured and analyzed using multi-component thrust measurement system. Engine performance was accurately evaluated by calculating the gross thrust of air breathing engine precisely which is analyzed from below serial procedure: labyrinth seal isolation, 1-axis gross thrust calculation, develop multi-component thrust measurement system, and side thrust analysis.

This paper is studied on the effect of the bolt joint stiffness on the Thrust Measurement Stand(TMS). TMS is a test stand for thrust performance of the propulsion system, which depends on two factors: The $1^{st}$ is the parallel degree between directions of the thrust vector and action lines of the corresponding measuring load cells for the vector, and the $2^{nd}$ is the orthogonality between action lines of the measuring load cells. Therefore, it is essential to maintain the original shape of the TMS under operating conditions. In this paper, it is examined how the geometric tolerance of the bolt joints and threads of the load cell trains affect the performance of the TMS. Also, some techniques to overcome related problems are proposed.
