Purpose: The kappa angles of human eye were measured by photographs. The relationship between the dominant eye and far refractivity is studied. Methods: 112 adults participated in this study. The mean age was $22.54{\pm}5.90$ years. The kappa angles were measured by the deviation of the flash image in the photographs of eye. the dominant eye and the far refractivity were analyzed. Results: The distributions of kappa angles were 78.6% (176 eyes) in the positive angle, 15.2% (34 eyes) in the negative angle, and 6.2% (14 eyes) in the $0^{\circ}$. The kappa angles were $4.50{\pm}4.70^{\circ}$ for the dominant eye, $4.93{\pm}4.34^{\circ}$ for the non-dominant eye, $+6.00{\pm}2.22^{\circ}$ for the hypermetropia, $4.91{\pm}4.97^{\circ}$ for the emmetropia, and $+4.61{\pm}4.49^{\circ}$ for the myopia. The biggest kappa angles was odserved in the hypermetropia and the angles was getting smaller in the emmetropia, and the myopia. Conclusions: The kappa angle of the dominant eye was smaller than non-dominant eye. The kappa angle was smaller as the far refractivity is lower. The kappa angle can be directly measured by the photographic method.

This work explores the historical transformation of manual landscape architectural drawings in terms of hybridization to uncover their inherent creative aspect. Landscape architectural drawing has duel functions; namely, scientific instrumentality and artistic imagination, which are relative, interchangeable, and transformable. These characteristics have been embodied in the forms of particular types of drawing, projections, perspective views, and diagrams, which are not so much clearly distinguishable as rather mutually complementary and hybridized. In particular, the pictorial views of plants in the forms of a perspective view or elevation were frequently hybridized to projection drawings of grounds and architectural structures, which is called planometrics. Particular drawing types have often emerged as suitable and thereby dominant forms, depending on the particular historical styles of landscape design. Sixteenth-century Italian Renaissance gardens and seventeenth-century French formal gardens were generally visualized in the form of projections. Eighteenth-century and early nineteenth-century English landscape gardens were frequently represented in a pictorial perspective view. In nineteenth-century America, different drawing techniques such as competition drawing, photography, and map overlay were specialized depending on their respective functions. Twentieth-century American modernists began to explore the diagram to deploy design strategies. In such transformation, however, the planometric, which considers both the ground plane and plant's frontal identities simultaneously and thereby is suitable to landscape design, was frequently used as a hybridization technique. In the mid-nineteenth century, a top view of plants replaced the planometric, and then, in the twentieth century, plants were no longer represented artistically, instead reduced to the forms of standardized flat symbols. The use of instrumental visualizations thereby gradually increased rather than the use of an imaginative representation for landscape architectural drawings.

This survey was carried out in Schneegattern Forest District which is located 40 km northeast of Salzburg, Austria. The purpose of interpretation with two sampling methods, stratified sampling and unstratified sampling, on B & W infrared photos, with a scale of 1:10,000 was to know coniferous stand volumn and to reduce the cost, Forest stands were classified into 4 groups; those were non-forest, young stands, beech, coniferous stands. Coniferous and beech stands were devided into age classes I (41-80 years), II (above 81 years). After this delineation sample points were designated on the orthophoto map whose data were transferred from the aerial photos. The volumn data were calculated from DBH using relascope in the field and the results were as follows. 1) Coniferous stand volumn per hactare was ($470{\pm}31.9m^3$ 2) The diameter distribution of $C_1$ was binomial, but $C_2$ showed normal distribution. 3) The stratified sampling method was better than unstratified sampling method.

Overlap what images are laid on top of each other performs various purposes of artistic expressions. Especially, overlap to describe motion has been placed on lots of art fields analysing and connecting each part of motion. This kind of overlap is called as 'Locomotive overlap' and it is defined as 'Technique for multiplication to arrange simultaneously motions of single object on one screen'. Locomotive overlap was started from fine art and photography, so this static kind of it is classified as 'Static locomotive overlap'. Afterwards, film and animation succeeded static locomotion overlap and realized real dynamic locomotive overlap with moving images, so this dynamic kind of it is classified as 'Dynamic locomotive overlap'. Most of all, by Norman McLaren accomplished its own artistic value and aesthetics in locomotive overlap has been placed in the center of the history of locomotive overlap, so to analyze this work and to research before and after it will confirm context and artistic achievements of locomotive overlap. Nowdays locomotive overlap is extending its technology and dimension more and more on the strength of development of digital technology. Some of works using digital technology show new possibilities of locomotive overlap by reinterpreting original media and concept of . Ultimately, this research for locomotive overlap focusing on the analysis of confirms artistic achievements of locomotive overlap and suggests to contemplate the meaning and new possibilities of it.

Background Rosa damascena, a type of herb, has been used for wound healing in Eastern folk medicine. The goal of this study was to evaluate the effectiveness of rose placenta from R. damascena in a full-thickness wound model in mice. Methods Sixty six-week-old C57BL/6N mice were used. Full-thickness wounds were made with an 8-mm diameter punch. Two wounds were made on each side of the back, and wounds were assigned randomly to the control and experimental groups. Rose placenta ($250{\mu}g$) was injected in the experimental group, and normal saline was injected in the control group. Wound sizes were measured with digital photography, and specimens were harvested. Immunohistochemical staining was performed to assess the expression of epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), transforming growth factor-${\beta}1$ (TGF-${\beta}1$), and CD31. Vessel density was measured. Quantitative analysis using an enzyme-linked immunosorbent assay (ELISA) for EGF was performed. All evaluations were performed on postoperative days 0, 2, 4, 7, and 10. Statistical analyses were performed using the paired t-test. Results On days 4, 7, and 10, the wounds treated with rose placenta were significantly smaller. On day 2, VEGF and EGF expression increased in the experimental group. On days 7 and 10, TGF-${\beta}1$ expression decreased in the experimental group. On day 10, vessel density increased in the experimental group. The increase in EGF on day 2 was confirmed with ELISA. Conclusions Rose placenta was found to be associated with improved wound healing in a mouse full-thickness wound model via increased EGF release. Rose placenta may potentially be a novel drug candidate for enhancing wound healing.

The lane-change behavior usually consists of discretionary lane-change and mandatory lane-change types. For the first type, drivers change lanes selectively to maintain their own driving condition and the second type is the case that the drivers must change the current lane, which can occur in recurrent congestion sections like merging and weaving sections. The mandatory lane-change behavior have a great effect on the operation condition of freeway. In this paper, we first generate data such as traffic volumes, speeds, densities, and the number of lane-change within the merging and weaving sections using the data of individual vehicle collected from time-lapse aerial photography. And then, the data is divided into the stable and congested flow by analyzing the speed variation pattern of individual vehicles. In addition, the number of lane-changing from ramp to mainline within every 30-meter interval is investigated before and after traffic congestion at study sites and the distribution of lane-changing at each 30-meter point is analyzed to identify the variation of lane-changing ratio depending on the stable and congested flows. To recognize the effect of mainline flow influenced by ramp flow, this study also analyzes the characteristics of the lane-changing distributions within the lanes of mainline. The purpose of this paper is to present the basic theory to be used in developing a lane-changing model at the merging and weaving sections on freeways.

Botulinum toxin type A is widely used for anti-wrinkling therapy, and correction of the square face. The toxin ultimately prevent the release of membrane-bound acetylcholine at the neuromuscular junction of striated muscles and thus produce chemical denervation and paralysis of the muscles. Our purpose of study is to know if application of botulinum toxin type A on calf reduction is effective, how much dosage is effective, and what are the possible complications. We reviewed data of 30 consecutive patients subjected to calf reduction in Dong-A University Hospital from February 2003 to April 2003. We injected normal saline 2cc on both calves region in 15 control group patients, and the other patients was divided 3 group. Group 1, Group 2, Group 3 was injected 50U, 100U, 150U botulinum toxin A on each calf region and followed up for 6 month. Maximal circumference of calf was not changed in the control group but an average of 0.7 cm reduction was noted in group 1, average 1.34 cm(right calf) and 1.26cm(left calf) in group 2, average 1.44cm(right calf) and 1.58cm(left calf) in group 3. Maximal area of calf was not changed in the control group but average reduction of 12.5%(right calf) and 12.7%(left calf) was obtained in group 1, average 19.4% (right calf) and 19.9%(left calf) in group 2, average 24.8%(right calf) and 21.07%(left calf) in group 3, as measured on CAT scan. Total fat amount and fat amount in the lower extremity was no change in all the groups, but lean body mass was decreased average 1.27%(right calf) and 1.15%(left calf) in group 1, average 3.47%(right calf) and 2.98%(left calf) in group 2, average 3.58%(right calf) and 3.95%(left calf) in group 3. Photography of the preoperative and postoperative 6 month state revealed higher satisfaction in Group 2, 3 compared to Group 1. Use of botulinum toxin type A in calf reduction is a very simple, safe, non-invasive method and effective in terms of calf contouring rather than reduction of calf circumference.

This study was carried out to classify and evaluate the land cover map using Landsat TM data in Pyeongtaeg City. DGPS data, aerial photography, topographical map were used for selection the training sets and accuracy assessment. The overall accuracy and Kappa coefficient of the land cover classification map(using supervised classification with 13 classes) with Landsat TM data(16 June. 1997) were respectively, 86.8%, 85.4%, but the user's accuracy of urban/village and vinyl-house was below 60%, and the producer's accuracy of read and vinyl-house below 70%. Maybe it was caused the spectral reflectance characteristics, heterogeneity and small distribution area on the artificial things such as urban/village, vinyl_house and road, etc. And then, the agricultural land cover classification system using remote sensing data in Korea was to classify level I and II. Level I consisted of 5 classes such as agricultural land, forest land, water, barren land, urban and built-up land.

The purpose of this study is to reveal spatial relationships between landslide and geospatial data set, to map the landslide susceptibility using the relationship and to verify the landslide susceptibility using the landslide occurrence data in Boun area in 1998. Landslide locations were detected from aerial photography and field survey, and then topography, soil, forest, and land cover data set were constructed as a spatial database using GIS. Various spatial parameters were used as the landslide occurrence factors. They are slope, aspect, curvature and type of topography, texture, material, drainage and effective thickness of soil. type, age, diameter and density of wood, lithology, distance from lineament and land cover. To calculate the relationship between landslides and geospatial database, Bayesian probability methods, weight of evidence. were applied and the contrast value that is >$W^{+}$->$W^{-}$ were calculated. The landslide susceptibility index was calculated by summation of the contrast value and the landslide susceptibility maps were generated using the index. The landslide susceptibility map can be used to reduce associated hazards, and to plan land cover and construction.

An expression of image in visual communication design traditionally has a dose relationship with the mechanical part of several expression media. Especially, an image conversion becomes easter by converging various forms of image such as a pictorial expression, a drawing up a plan, an optical expression and a reflected image into digital data in the image expression using digital mode. In addition, synthesis between various forms of visual ,images is activated by the integration of all expression media into digital mode and thus the extent of the image expression becomes diversified. Moreover, there is a tendency that a various dimensional expression such as 3D and 4D is generalized in the image expression of digital design. A partial or whole image conversion has often occurred during the generalization process of several image forms. Such conversion summarized into two factors, a formative side and a technical side. We described the existing pictorial expression as a formative side, an optical expression as a photography, a materialization of image conversion theory of computer graphic image conversion according to data form as a technical side and specific content according to dimension. We summarized objective and demonstrative resets through a simple simulation using a computer for the contents required a technical and qualitative measure and presented an application program of the particular results from the study to the visual communication design work by a case.
