Objectives : Chungsimyeonja-eum (CSYJE; Qingxinlianzi-yin in Chinese; Seishinrenshi-in in Japanese), a traditional herbal medicine, has been used for treating mouth dryness, hyperuresis. This study was designed to determine preservation period of CSYJE. We investigated the stability and biological activity of CSYJE depending on the preservation temperature and periods. Methods : CSYJE decoction was preserved for 0-6 or 12 months at room temperature (RT, $23{\pm}1^{\circ}C$) or refrigeration ($4^{\circ}C$). To evaluate the stability of CSYJE decoction, pH and dissolved solids content were measured. High-performance liquid chromatography (HPLC) analysis was performed to determine marker compounds-liquiritin apioside, liquiritin, baicalin, wogonoside, and glycyrrhizin-in CSYJE. To determine anti-inflammatory effect of CSYJE, prostaglandin $E_2$ ($PGE_2$) was measured in LPS-stimulated RAW 264.7 macrophages. Results : Both at RT and $4^{\circ}C$, pH was decreased depending on the preservation periods. There was no changes in dissolved solids content depending on the preservation temperature and periods. Both at RT and $4^{\circ}C$, the contents of liquiritin apioside and liquiritin were slightly increased at 1 month of storage. The level of baicalin was decreased time-dependently and the disappearance rate at RT is larger than at $4^{\circ}C$. CSYJE inhibited $PGE_2$ production in LPS-stimulated RAW 264.7 cells and maintained inhibitory effect by 12 months both at RT and $4^{\circ}C$. Conclusions : Based on the disappearance rate of the baicalin in CSYJE, the preservation period is recommended within 8 months for RT and 12 months for $4^{\circ}C$.

(1986) and (1987) represent the society of 1980s in which the professional baseball game was initiated to cover the irrational military culture. The love and marriage of sports players were the headlines of the media, and the yearly salary of the players was the hottest issue of conversation. The military culture is represented in the scenes where the coaches train the failures and inapt players in extreme drills. The films pinpoint the absurdity of military culture and win-at-all-costs mentality. The collapse of the dictatorial leadership at the end of the films is a metaphor for the collapse of the fifth Republic of Korea. The episodes where the players talk about contract money, and the trade of players and sports business were a new phenomenon of the 1980's. The fact that Oh Hyesung of chooses love instead of victory deals a big blow to the secular ambition for money, victory and dictatorial leadership. His option provides catharsis for an audience oppressed under military leadership and success driven ideology. On the other hand, Oh Hyesung of dies right at the moment of winning the world champion. He achieves neither love nor success. While Oh Hyesung of is a symbol of pure love and gives spiritual comfort to the audience, Oh Hyesung of gives a sense of hopelessness to the audience. Both of the two sports films reflect the representation of the 1980's but received opposing reviews from audiences.
