  • This study aimed to investigate the impact of light intensity, manipulated through different shading levels, on the growth and physiological responses of Thermopsis lupinoides. To assess the effects of shading treatments, we examined leaf mass per area, chlorophyll content, chlorophyll fluorescence response, and photosynthetic characteristics. T. lupinoidesexhibited adaptive responses under low light conditions (50% shading), showing increased leaf area and decreased leaf mass per area as shading levels increased. These changes indicate morpho-physiological adaptations to reduced light availability. At 50% shading, the physiological and ecological responses were favorable, with optimal photosynthetic functions including chlorophyll content, photosynthesis saturation point, photosynthetic rate, carbon fixation efficiency, stomatal conductance, transpiration rate, and water use efficiency. However, at 95% shading, the essential light conditions for growth were not met, significantly impairing photosynthetic functions. Consequently, 50% shading was determined to be the most optimal condition for T. lupinoides growth. These findings provide valuable insights for effective ex-situconservation practices and site selection for T. lupinoides, serving as foundational data for habitat restoration efforts.

  • To evaluate the effects of Zoletil (tiletamine- zolazepam) that have been widely used for the chemical restraint and anesthesia of primates, on physiologic alteration, blood gas analysis and anesthetic duration in the Japanese macaque(Macaca fuscata), this study was carried out. Zoletil was administered by intramuscular injection. Evaluation of temperature, heart rate, respiration rate and blood gas analysis were performed before administration and at 1, 10, 20, 30, 40, 50 and 60 min after administration, and induction and maintenance time was recorded. There was no significant difference in heart rate, $PCO_2$, $PO_2$ after Zoletil administration rut temperature, respiraticn rate, pH were significant difference compared with these of Mere administration. The induction time was $2.5{\pm}1.0min$ and maintenance time was $86{\pm}23.2min$. It was considered that Zoletil could be usefully used for the sedation and immobilization of Japanese macaque reared in zoological garden.

  • Eclipta prostrata and E. alba are annual herbal medicinal plants and have been used as Chinese medicinal tonics. Both species are widely distributed in tropical and subtropical regions as well as in Korea. Both species have similar morphological features but E. alba has smoother leaf blade margins compared with E. prostrata. Although both species are utilized as oriental medicines, E. prostrata is more widely used than E. alba. Morphological semblances have confounded identification of either species. Here, we report the complete chloroplast genomes of both species to provide an authentication system between the two species and understand their diversity. Both chloroplast genomes were 151,733-151,757 bp long and composed of a large single copy (83,285-83,300 bp), a small single copy (18,283-18,346 bp), and a pair of inverted repeats (25,075-25,063 bp). Gene annotation revealed 80 protein coding genes, 30 tRNA genes and four rRNA genes. A phylogenetic analysis revealed that the genus Eclipta is grouped with Heliantheae tribe species in the Asteraceae family. A comparative analysis verified 29 InDels and 58 SNPs between chloroplast genomes of E. prostrata and E. alba. The low chloroplast genome sequence diversity indicates that both species are really close to each other and are not completely diverged yet. We developed six DNA markers that distinguish E. prostrata and E. alba based on the polymorphisms of chloroplast genomes between E. prostrata and E. alba. The chloroplast genome sequences and the molecular markers generated in this study will be useful for further research of Eclipta species and accurate classification of medicinal herbs.

  • This study was performed with an aim to examine the inner thoughts of Muso Soseki through his works. In this study, we reviewed currently existing Mus$\bar{o}$ Soseki. Works in which his idea or intention behind his works are to be understood in terms of landscaping science or religious perspective. Targeting his best representative works of temple gardens such as Jochou-ji, Eiho-ji, Zuisen-ji, Tenryu-ji, it was sought his view of gardening and technique of garden making. Those temples, selected as target of this study, have significance as a places to have started his learning till matured of his thought into his gardening works. What we need to concentrate and think about regarding the works of Muso is the fact that we are to be impressed upon just looking at his works. The study result indicates that Muso not only symbolized his various mastered ideas & philosophies into spatial configuration into the garden based on Zen Buddhism idea, but also accomplished the Sabi-gardening beauty. Through his writing "Mongjoongmundap(夢中問答)" that is created using his core thoughts, his works can be understood better. This study has significance in that the idea. It could be understood that Muso's work is rooted in the basic idea of three ideas. The first of it is Zen philosophy being indicated in his configuration of gardening such as Zen meditation Stone, cave, chamdo etc. The second of it is shown as the merciful heart of Sangguboje(上求普提), Hahwajoongsaeng(下化衆生), being indicated in his configuration of gardening such as the pond And finally, there appears the Tao idea. Taoist thought has become of where the background space.

  • This study was conducted to develop the suitable plant mat for garden mum. The results about growth 2 months after cutting of garden mum (Dendranthema grandiflorum 'White Miri') under 6 different plant-mat treatments using coir tape were as follows. The majorities of cuttings were withered under treatments of non-soiled 15 mm thick mat (C treatment). On the other hand, the same thick mat having a hole filled with soil 3 mm in diameter (D treatment) and the 30 mm thick mat having a hole filled with soil (F treatment) showed the best growth results. The survival rates of treatments D and F showed the higher rates of 100 and 90%, respectively than those of respective 56.3 and 20% of two layers without medium (A treatments) and C treatment having respective 10 and 15 mm thick non-soiled mats. The plant height showing the similar tendency with the result of the survival rate was shown with the lower value of 7.97 and 7.15 cm, respectively under treatments A and C, compared with the higher value of 9.74 and 9.80 cm respectively under treatments D and F. For flower gardening, it is better to adopt treatment D based on the our investigational results that treatment D required less soil than treatment F and had no trouble with forming adventitious roots for manufacturing mats and effective transferring.

  • This study attempted to eatablish a High Performance Liquid Chromatography (HPLC) analysis method for the determination of (-)-epicatechin gallate as a part of the quality control for the development of functional cosmetic materials from Penthorum chinense Pursh. HPLC was performed on a Unison $US-C_{18}$ column ($4.6{\times}250mm$, $5{\mu}m$) with a gradient elution of 0.05% (v/v) trifluoroacetic acid (TFA) and methyl alcohol at a flow rate of 1.0 mL/min at $30^{\circ}C$. The analyte was detected at 280 nm. The HPLC method was performed in accordance with the International Conference on Harmonization (ICH) guideline (version 4, 2005) of analytical procedures with respect to specificity, precision, accuracy, and linearity. The limits of detection and quantitation were 0.11 and 0.33 mg/mL, respectively. Calibration curves showed good linearity ($r^2$ > 0.9999), and the precision of analysis was satisfied (less than 0.6%). Recoveries of quantified compounds ranged from 99.51 to 101.92%. This result indicates that the established HPLC method is very useful for the determination of marker compound in P. chinense Pursh extracts.
