  • The purpose of this paper is the analysis of to point its structure and meaning deduced from the rite of passage. In the light of the rite of passage, could be retrieved its value as one of significant works among the works of Gangho-sijo. is composed of nineteen pieces of monotype sijo. The first piece is a kind of prologue. The other pieces are divided into three parts which correspond with the three stages of the rite of passage-separation, transition, incorporation. As a result of this analysis, we can find out the writer's cognitive change according to the schema of the rite of passage. It becomes clear that the space of Gangho means the sacred space for mental culture rather than a separate space for escape. And considering the withdrawal for Gangho as the transition process of the rite of passage, gives a description of the disentanglement of conflict and a incorporation into the superior position of spirit.

  • This paper deals with a reference model for a process-oriented parts supply company From the view point of SCM(Supply Chain Management), the model focuses on the integration of order management and manufacturing information. The model, considering the characteristics of manufacturing processes, separates the execution level from the planning level, and then introduces a virtual process to efficiently link the two levels. The model is operated to maximize its flexibility by the separation of planning and execution. A case study shows that our model significantly increases the productivity of the company.

  • This study investigated ginsenosides and tissue characteristics of roots injured by physiological disorder, rusty and rough skin. After separation to cortex and stele parts of healthy, rusty (red) and rough skin roots, respectively, the contents of saponin and ginsenosides were analyzed. And also, the histological and cytological characteristics of cortex and stele parts were investigated. Crude saponin contents were little different among healthy, rusty (red) and rough skin root and ginsenesides as - Rgl, - Re and - Rbl were largely detected both in stele and cortex part. The ratio of PT/PD showed about 1:1 in three kinds of root. In histological study, destoryed cells in epidermis of rusty(red) root, and those in epidermis and exodermis of rough skin root were observed. The cells in cortex of rusty (red) and rough skin root have generally nucleus with unfixed shape, unequal cell wall, large number of vacuole and mitochondris, and unidentified dark substances compared to healthy root. But in cell of stele tissue, most of organellE seems to be normal except a small number of cells in rough skin root.

  • Snap-fit is being used in manufacture of plastic products. Integral features using snap-fit are classified as locks, locators and enhancements. Locking features complete the process of attachment by providing physical interference to prevent separation. Looking feature pairs consist of two components, i.e., a flexible latch and a rigid catch and require particular care and attention for their selection. We can make several locking feature pairs by selecting latch and catch, but some parts restrict freedom of selection. Therefore, part designers must know the characteristic properties of generic locking feature forms as considering a specific design problem. In this paper, it has been presented about problem of small size products using locking feature and then introduced new locking feature applicable to small parts.

  • The chromatographic separation of the MeOH extract of the aerial parts of Solidago virga-aurea var. gigantea $M_{IQ}$ . (Compositae) led to the isolation of six terpenoids and four phenolic compounds, trans-phytol (1), ent-germacra-4(15),5,10(14 )-trien-1$\alpha$-ol (2), $\beta$-amyrin acetate (3), ent-germacra-4(15),5,10(14)-trien-1$\beta$-ol (4), $\beta$-dictyopterol (5), oleanolic acid (6), kaempferol (7), kaempferol-3-O-rutinoside (8), methyl 3,5-di-O-caffeoyl quinate (9), and 3,5-di-O-caffeoyl quinic acid (10). Their structures were established by chemical and spectroscopic methods. Compounds 4, 5, and 10 showed moderate cytotoxicity against five cultured human tumor cell lines in vitro with its E $D_{50}$ values ranging from 1.52∼18.57 $\mu\textrm{g}$/mL.L.

  • Column chromatographic separation of the MeOH extract from the aerial parts of Paris verticillata led to the isolation of three phenolics, two terpene glucosides and two pyrrolidine alkaloids. Their structures were characterized to be methyl caffeate (1), 5-hydroxy pyrrolidin-2-one (2), vanillic acid (3), benzyl alcohol glucopyranoside (4), (6S, 9R)-roseoside (5), staphylionoside H (6) and 5-methoxy pyrrolidin-2-one (7) by spectroscopic means. The isolated compounds (1-7) were for the first time reported from this source. The isolated compounds were tested for their cytotoxicity against four human tumor cell lines by SRB method in vitro.

  • The inlet flow of centrifugal blower were quantitatively visualized using particle image velocimetry. Because the centrifugal blower system is one of the key parts of EV battery cooling system, the quantitative information of flow field of centrifugal blower is important to design and optimize the cooling system. Two types of inlet parts were used in this study. One is the straight inlet and the other is a bended one. The results showed the flow asymmetry exists in the straight model due to the pressure difference in the blower. In case of the bended one, the separation bubble and the increase of head loss appeared compared with the straight model.

  • Activity-guided separation for the aerial parts of Rodgersia podophylla A. Gray gave a new acylated flavonoid, quercetin 3-O-${\alpha}$-L-(5$^2$-acetyl)-arabinofuranoside (1), together with six known flavonoids (2-7). Their hepatoprotective activities were determined by using the primary cultures of rat hepatocytes injured by H$_2$O$_2$. Quercetin 3-O-${\alpha}$-L-(3$^2$-acetyl)-arabinofuranoside (3), kaempferol 3-O-${\alpha}$-L-rhamnopyranoside (5) and quercetin 3-O-${\alpha}$-L-rhamnopyranoside (6) exhibited hepatoprotective activities comparable to silybin at the concentration of 50 mM (45.7, 50.8 and 57.3 %, respectively), and the new flavonoid 1 showed hepatoprotective activity at the concentration of 100mM (50.1%).
