The soluble paclitaxel was found in the supernatant of the plant cell cultures of Taxus chinensis, The percentage of soluble paclitaxel depends on paclitaxel concentration in bioreactor. As paclitaxel concentration decreases the percentage of soulbe paclitaxel increases. it is therefore important to develop a new process for the recovery of soluble paclitaxel. The use of hydrophobic resin HP20 gives nearly perfect recovery of paclitaxel in supernatant. The resin was more effective in treatment of th cell and debris free filtrate probably because of the reduced solids content In this case 3 g.l resin and 1 day reaction were enough for recovery the soluble paclitaxel in medium.

This study focused on relationships among leisure involvement, experience quality and behavioral intention in the urban parks. A total of 335 were collected, and during the data refinement process, 39 questionnaires were eliminated from the study due to partial and inconsistent responses. thus leading to 296 usable questionnaires out of 335. In the final result, 296 questionnaires were coded for the analysis purpose. The hypothesized conceptual model was used to analyze the Descriptive Analysis and Frequency Analysis, Exploratory Factor Analysis, and Multiple Regression Analysis using SPSS 24.0. The result indicated this: residents' experience quality in urban parks depends on more attraction and centrality of leisure involvement than on the self-experience quality of leisure involvement. The results of this study also indicate that not all experience dimensions are important for resulting in positive behavioral intentions to urban parks. The quality of education, esthetic, and escape experience showed a significant predictor of behavioral intentions, while the quality of entertainment experience did not show a significant positive relationship with behavioral intentions.

The present study examines how to construct a transport system for tourism in the marine city area of Yeosu. An effective tourism transport system is needed in Yeosu to promote ocean tourism in Korea's southern coastal region. The problems in Yeosu's transport system for ocean tourism were identified by comparing it with the Bay Area in the United States; future improvement methods were deduced accordingly. The transport support system for ocean tourism in Yeosu area was insufficient in many aspects compared with the Bay Area, such as intercity transportation, urban transport systems, and transport information systems. Thus, this study suggests various approaches to building a new ocean tourism transport support system in Yeosu. Connecting transport modes and ocean tourism resources, such as linking intercity and urban transport modes with ocean tourism transport modes, is suggested. It is also recommended that a cooperative transport support system be established for ocean tourism in the neighboring regions of Yeosu. Furthermore, an integrated transport information system for ocean tourism needs to be provided to connect the system efficiently with ocean tourists. This integrated transport support system could lead to a decrease in the cost and time needed for travel.

The intraocular pressure for Korean youth were measured by using tonometer (AT555-Reichert). The relative frequency distributions of intraocular pressures have been studied for samples of 1,027 persons(475 males, 552 females). The most commonly recorded IOP for both men and women was around 14.5mmHg and 17.5mmHg, respectively. They were in the range of 7 to 23mmHg(males) and 7 to 22mmHg(females). The median pressure(cumulative frequency=0.5%) is 13.0~16.5mmHg for males and 16.5~18.5mmHg for females, so the values for females are slightly higher than males. The mean pressure is 15.2mmHg for males and 15.8mmHg for females, respectively. The 98% of population was in the range of the normal IOP. There are long-term diurnal variation in mean intraocular pressure and the IOP was decreased as a function of time from morning to night. The measured IOP was affected by several factors: exercise made to decrease the IOP and tight collars, dark places and posture of decubitus position got to elevate the IOP.
