This study has been accomplished as a experimental study for field application of 3D Perspective Image Map creation using Digital Topographical Map and based on the Ortho-Projection Image which is generated from Satellite Overlay Images and the precise Relative Coordinates of longitude, latitude and altitude which is corrected by GCP(Ground Control Point). AS to Contour Lines Map which is created by Coordinate conversion of 1:5,000 Topographical Map, we firstly made Satellite Image Map to substitute for Digital Topographical Map through overlapping the original images on top of each Ortho-Projection Image created and checking the accuracy. In addition to 3D Image Map creation for 3D Terrain analysis of a target district, Slope Gradient Analysis, Aspect Analysis and Terrain Elevation Model generation, multidirectional 3D Image generation by DEM can be carried out through this study. This study is to develop a mapping technology with which we can generate 3D Satellite Images of a target district through the composition of Digital Maps and Facility Blueprint and arbitrarily create 3D Perspective Images of the target district from any view point.

Purpose: The aim of this study was to evaluate the impact of polydeoxyribonucleotide (PDRN) on histologic outcomes when implant placement and lateral sinus floor elevation are performed simultaneously. Methods: Three bimaxillary premolars (P2, P3, and P4) were extracted from 4 beagle dogs 2 months before lateral sinus floor elevation. After lateral elevation of the sinus membrane, each sinus was allocated to either the test or control group. Sinuses underwent either 1) collagenated synthetic bone graft with PDRN following lateral sinus floor elevation (test group) or 2) collagenated synthetic bone graft without PDRN after lateral sinus floor elevation (control group). Eight weeks after the surgical procedure, all animals were euthanised for a histologic and histomorphometric assessment. Augmented height (AH), protruding height (PH), and bone-to-implant contact in pristine (BIC_p) and augmented (BIC_a) bone were measured. The composition of the augmented area, which was divided into 3 areas of interest located in coronal, middle and apical areas (AOI_C, AOI_M, and AOI_A), was calculated with 3 parameters: the area percentage of new bone (pNB), residual bone graft particle (pRBP), and fibrovascular connective tissue (pFVT). Results: AH, PH, BIC_p, BIC_a total, BIC_a coronal, and BIC_a middle values were not significantly different between sinuses in the control and test groups (all P>0.05). The BIC_a apical of sinuses in the test group (76.7%±9.3%) showed statistically higher values than those of sinuses in the control group (55.6%±22.1%) (P=0.038). pNB, pRBP, and pFVT showed statistically significant differences between the 2 groups in AOI_A (P=0.038, P=0.028, and P=0.007, respectively). pNB, pRBP, and pFVT in AOI_C and AOI_M were not significantly different between samples in the control and test groups (all P>0.05). Conclusions: The histologic findings revealed that lateral sinus floor elevation with PDRN might improve early new bone formation and enable higher bone-to-implant contact.

The equilibrium theory of island biogeography describes that the number of species on an island is determined by two factors, island area and distance from mainland acting through extinction and immigration rates. I was analysed the relationships between species number and island area, latitude, and maximum elevation for butterflies on 71 islands in the Korean Peninsula. Among Korean islands, island area ($r^2$=0.405, P< 0.005) and habitat diversity ($r^2$=0.341, P<0.005) were significantly correlated, but distance from mainland ($r^2$=0.018, P>0.05) and latitude ($r^2$=0.040, P>0.05) were weakly correlated. The present and earlier studies on the butterfly species richness in Korean islands demonstrate that the butterfly fauna is closely related to the ecological variables, i.e., area, composition of flora and maximum elevation.

The study investigates herbage communities along the altitudinal gradient in northwest Himalaya and highlights the effect of trees on its understory floristic diversity and phytosociology. The study was conducted in nine forests at three elevations viz., chir pine (Pinus roxburghii), mixed and khair (Acacia catechu) forests at elevation $E_1$ (850-1150 m), chir pine, mixed and ban oak (Quercus leucotrichophora) forests at elevation $E_2$ (1151-1600 m) and ban oak, mixed and chir pine forests at elevation $E_3$ (>1600 m) in a sub-watershed located in Solan district of Himachal Pradesh, India. These were compared grasslands located adjacent to forests. In all, 20 grass, 3 sedge, 2 forb and 4 legume species were recorded in study sites. Jaccard's coefficient of herbage vegetation was highest between chir pine forests and grasslands, and lowest in khair and ban oak forests. TWINSPAN dendrogram of herbage composition exhibited three subtypes with Apluda mutica, Arundinella nepalensis and Dichanthium annulatum as indicator species. Three groups of plant communities were identified on the basis of their moisture requirement. Peak density and basal area of herbage in forests and grasslands occurred by September. Density and basal area of herbage in grasslands at different elevations ranged from 649.6 to $1347.9tillers/m^2$ and 30.0 to $65.7cm^2/m^2$, respectively, while, in forests it varied from 351.2 to $1005.3tillers/m^2$ and 14.9 to $43.9cm^2/m^2$, respectively. Density and basal area of the herbage in plant communities decreased along the elevation. Under trees in forests the density of herbage decreased up to 77% and basal area up to 62% of their respective values in grasslands.

In the phase of an architectural designing, the Pinakothek der Modeme in Munich is considered that it is influenced by the Altes Museum in Berlin. The critical elements were composed of the classification of Tominaka and my points of view. Two buildings were analyzed for comparison by six elements, such as, a spatial construction, an organization of plan, an organization of section, a composition of elevation, a method of construction and a composition of mass. The results of the analysis were that the design of the Pinakothek der modeme was influenced by the Altes Museum as follows: 1)the use of square and circle in the composition of plan, 2)the use of a curtain of columns and a formation of the transitional space between columns and front wall, 3)the location and function of the main stairs and the inner court, 4)the arrangement of exhibition halls, 5)the covering of dome, 6)the unification of spaces of different floors through the rotunda. This study may be helpful for any architects who make a decision of the method and the range of reference to some other building in the beginning of design.

The meaning of the space planning which has from modern interior space has played important role, space composition planning itself is the concept creation tool as well as the unique expression sphere in field of interior space far away from fixed idea relevant to the existing space which was only simple division or secondary element in design. Thus, this current work expresses that the space-Function is related with space-division as well as basic designed-conceptual work process including the space is formed. Furthermore, through the side-composition with form, it activates the various space aspect perceptually, which created the visual environment in using lightning, reflection of glass and penetrated nature etc. The keyword on elevation design concept is as like various aspects, third dimension, non-materiality and symbolical meaning. In addition, it provides the color space equipped with functionality and artistry capable to arouse the diverse sensual capacity to space users on default of image language.

Though a reactive distillation column reduces energy requirement and gives easy separation of azeotropic mixture to result in wide practical applications in field, its design is difficult. On the other hand, a commercial design software used largely in chemical process design and performance evaluation can solve the problem, but the addition of reaction into the tray is not simple. In this study the addition is implemented to make the process simulation available, and it is utilized in the design of a TAME process to find the following design guidelines. The addition of reactive trays gives more composition elevation than the composition decrease from the reduction of the trays, and the increase of non-reactive trays does not improve product quality. The elevation of reboiler heat duty lowers the product quality by the reduction of residence time in reactive tray and conversion.
