這篇文章是關丁韓中兩國傳統社會襄醫員的社會地位的論文. 在這篇文章通過韓中兩國社會的區別点來析韓中兩國傳統社會醫員的地位. 結論就是韓國傳統社會比中國傳統社會還閉鎖, 而韓國傳統社會醫員的社會的地位比中國還底一些.

This study was performed to investigate the behavior of vapor phase of fuel mixtures with different piston bowl shapes(F, B and R-type) in a optically accessible engine. The images of liquid and vapor phases were captured in the motoring engine using exciplex fluorescence method. Fuel was injected into atmospheric nitrogen to prevent quenching phenomenon by oxygen. Injection pressure was 5.1MPa. Two dimensional spray fluorescence image of vapor phase was acquired to analyze spray behaviors and fuel distribution inside of cylinder. Four injection timings were set at BTDC 90$^{\circ}$, 80$^{\circ}$, 70$^{\circ}$, and 60$^{\circ}$. With a fuel injection timing of BTDC 90$^{\circ}$, fuel-rich mixture level in the center region was highest in a B-type piston. With a fuel injection timing of BTDC 60$^{\circ}$, R-type piston was best. R-type piston shape was suitable under enhanced swirl ratio and late injection condition and B-type piston shape was right in a weak swirl ratio. It was found that the piston bowl shape affected the mixture stratification inside of cylinder.

Injection pressure is 5.1MPa. Two dimensional spray fluorescence image of vapor phases was acquired to analyze spray behaviors and fuel distribution inside of cylinder. Four injection timings were set at BTDC $90^{\circ},\;80^{\circ},\;70^{\circ},\;and\;60^{\circ}$. With a fuel injection timing of BTDC $90^{\circ}$, fuel-rich mixture level in the center region was highest in a B-type piston. With a fuel injection timing of BTDC $60^{\circ}$, R-type piston was best.

${\ll}$Bangyakhappyeon(方藥合編)${\gg}$ was written by Hwang Do-Yeon (黃度淵) and his son Hwang Pil-Soo (黃泌秀) in the late days of Chosun Dynasty, when the country was in a state of social confusion by the first introduced western civilization and invasion of the foreign powers. In response to this situation where realistic knowledge and solution was of importance than theological review, Hwang and his son wrote the book to satisfy the needs. The book, ${\ll}$Bangyakhappyeon(方藥合編)${\gg}$ furthered new publishment of abstract asian medical science in a more compact form, emphasizing more realistic means of it. This new publishment were a significant counter-measure to cope with the inflow of practical western medicine, which the move has moreover enhanced popularization of Han Medicine(韓醫學). After reviewing ${\ll}$Bangyakhappyeon(方藥合編)${\gg}$ in xylographical approach, I have acquired conclusions as below.
