  • The fine structure of the callus induced from epidermis of Panax ginseng leaves cultured on Murashige & Skoog medium plus kinetin 0.1mg/l, NAA 0.2mg/l and 2.4-D 0.5mg/l was observed. The cells composing callus tissue are mononucleus. Three types of cells were identified; cells with abundant cytoplasm, cells with relatively differentiated vacuoles and with numerous starch grains in the plastids and ones with highly differentiated vacuoles and with unsaturated lipid granules. Prolamellar body, plastid lamellae, plastid globules, stromacenter, fine tubules, crystal-containing body and DNA-like structures were observed in the stroma of the plastids. The chromoplasts were identified in some cells believed as the mother cells of secretory cells in secretory ducts. Curved or straight micro-fibrils of 100~150A in diameter were observed in the cytoplasm. And the characteristics of cell organelles and cell inclusions and the vacuole formation in callus tissues were discussed.

  • This study has been carried out to investigate the differences of compressional properties in various wool fabrics which have different structural conditions in composing ratio of wool fabric, count of material yarn and cloth count of fabric. The result of the study are summarized as follows ; 1. The wool fabrics woven with lower with lower count yarn are superior to those woven with higher count yarn in the property of compression and resiliance of compression. 2. All wool fabrics are superior to polyester/wool blended fabrics in the property of compression and inferior in the linearity. 3. In general as the cloth count of fabrics increases, the percentage of compression decrease and the linearity increases proportionally in wool fabrics.

  • The purpose of this study is to classify twenties males'lateral body shapes into a few representative types and to give each type a name to symbolize its typical shape clearly .297 male subjects in their twenties participated in this study. 33 anthropometric and 31 photographic measurements were taken from each subject. The data were reduced to 7 factors. The factor score composing the lateral body shapes was classified into 3 clusters. As the result the lateral body shapes of the males were classified into I, S, types.

  • An output feedback control (OFC) is presented for a linear stochastic system with known disturbance and applied to a flexible spacecraft for the reduction of residual vibration while allowing the natural deflection during operation. By converting the tracking problem into regulator problem, the OFC minimizes the expected value of a guadratic objective function composing of error stats which always remain on the intersection of sliding hypersurfaces. For the numerical evaluation with a flexible spacecraft, a large slewing maneuver strategy is devised with a tracking model for nominal trajectory and start-cost-stop strategy for economical maneuver in conjunction with the input shaping technique. The performance and efficacy of the proposed control scheme are illustrated with the comparison of different maneuver strategies.

  • This study investigated the effects of story making activity with wordless picture books on the language abilities of 5- and 6-year-old children. The 52 subjects attending a kindergarten in Kwangju were randomly assigned to an experimental group or a control group of 26 children each. The experimental group made stories with wordless picture books while the control group listened to stories. Experimental treatments were given twice a week for 6 weeks. Assessment was by The Language Comprehension-Cognition Test(1994), The Picture Vocabulary Test(1995), and The Sentence-Comprehension Test(1996). Qualitative level of the stories was analyzed by Morrow's(1985) revised Instrument Assessing Children Understanding of Stories(Chae, 1996). The vocabulary, language-comprehension, and story-composing ability of children who made stories with wordless picture books were higher than those of children who listened to stories told by teachers.

  • The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of the architectural buildings, and this space imagery is created here by all the space composing elemensts of the building. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. The present building is going with Eco-Architecture. When 2008 sees the building,,Eco-Architecture design which hits appears. There is a possibility of seeing 16 kind types from that place. And From here examined the spatiality which is expressed. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer. It's way to help in architectural design and wishes.

  • This paper describes a method of stereo image composition for mixed reality without camera calibration or complicate tracking algorithm. The proposed system tracks the panel which has blob makers, and composes virtual objects naturally using the method of texture mapping which is often used in geological computer graphics mapping when we do mapping 2D computer graphic data or man-made 2D images. The proposed algorithm makes it possible for us to compose virtual data even in the case that the panel is bent. For composing 3D object, the system uses depth information obtained from stereo image so that we do not need cumbersome procedure of camera calibration.

  • The Yellow River began ceasing affected by natural factors and the unreasonable human activities. The flow broke in the Yellow River and water and sediment flowing into the sea decreased, which lowered the speed of newly formed wetland extending to the sea. The water environment deteriorated; Its composing structure tended to be unsteady; The biologic diversity decreased and wetland function reduced. To ensure that the Yellow River delta and its ecosystem develops sustainablly, it is significant to reduce times and days of the ceasing, keep certain runoff and sediments in the river to the sea and make its watercourse stable.

  • Large-scaled apartment housing complex at outskirts of downtown which has direct influence on urban view concentrated on improving the space outside the complex like spatial composition of individual plan design, but neglected the contribution of urban view. However, as people's orientation toward urban areas was changed to quality from quantity, concerns on urban view have been gradually increased and planning of apartment housing has been extended to complex with view contributing to urban people as a factor composing the city in resident centered spatial composition. This study is therefore to examine the characteristics of view components of 13 apartment housing complexes at Sangmu District in Gwangju Metropolitan City and their influences on evaluating view image.

  • Architecture should deviate from euclidean ideas of abstract space while helping to accommodate individual perceptions and experiences of a given space. Concepts for making space should be cognitively processed. The process of gathering information from the environment represents a new spatial concept as expressed in the cognitive structural relationship between the environment and the individual as the subject of architecture. Additionally, the cognitive experience of space is primarily perceived visually, and visual perception is the basis for information-gathering and decision-making. Therefore architecture should be excluded from the conceptual focus on the existing space design rules, being expressed instead in experimental architectural spaces connected to subjective human experience. While some research has been done on this topic regarding architecture, further study is required in the area of interior design. This study proposes the possibility of composing effective living space through an investigation of cognitive space concept theory and expression elements, and includes a case study of Interior architectural spatial analysis.
