  • The speckle photography technique is one of the novelest velocity measurement methods. This study examines the possibility that this technique will become practically applicable. In this study, LSP is applied to the fine water mist spray. Moreover, a He-Ne gas laser is employed as the light source in order to enhance the validity of this technique. It becomes clear that this technique using a He-Ne gas laser can obtain a whole instantaneous two-dimensional velocity distribution and also apply to test the performance of fine water spray.

  • This study proposed detection method of Marine debris using unmanned aerial photography. For unmanned aerial photography, a RC(Radio Control) helicopter which has good movability and economics was used. To a camera mounting, a gimbal equipment was attached to the bottom of the RC helicopter. The gimbal equipment is very useful because it is not seriously affected by vibration and rolling. In addition, we invented that digital image processing algorithm using Matlab program for detection of marine debris from photographs. Particularly, background subtraction in invented algorithm was applied. As a result, marine debris of a variety of forms from different sand states of coast were reliably detected. In the future, monitoring using proposed method was expected to contribute that the solution to representative problem of monitoring area selecting and estimate the total litter mass over the beach. Moreover, It is considered a greater application possibility to marine environmental observations.

  • The rational polynomial coefficients(RPC) model is a generalized sensor model that is used as an alternative for the physical sensor model for IKONOS-2 and QuickBird. As the number of sensors increases along with greater complexity, and as the need for standard sensor model has become important, the applicability of the RPC model is also increasing. The RPC model can be substituted for all sensor models, such as the projective camera the linear pushbroom sensor and the SAR This paper is aimed at generating a RPC model from the physical sensor model of the KOMPSAT-1(Korean Multi-Purpose Satellite) and aerial photography. The KOMPSAT-1 collects $510{\sim}730nm$ panchromatic images with a ground sample distance (GSD) of 6.6m and a swath width of 17 km by pushbroom scanning. We generated the RPC from a physical sensor model of KOMPSAT-1 and aerial photography. The iterative least square solution based on Levenberg-Marquardt algorithm is used to estimate the RPC. In addition, data normalization and regularization are applied to improve the accuracy and minimize noise. And the accuracy of the test was evaluated based on the 2-D image coordinates. From this test, we were able to find that the RPC model is suitable for both KOMPSAT-1 and aerial photography.

  • This case report determines the effects of Korean medicine treatment on a pontine hemorrhage with a cavernous malformation. In this study, Korean medicine treatments, such as herbal medicine, acupuncture, electro-acupuncture, and moxibustion, were administered for 30 days. During the hospitalization period, evaluations were performed using the Scott and Kraft Scale, eye movement, 9-gaze photography, the House-Brackmann grading system, and Yanagihara's unweighted grading system on days 1, 12, and 30. The Scott and Kraft Scale increased from -4 to -2, while eye movement increased from 43.1% to 72.3%. The House-Brackmann grading system improved from 4 to 2, and Yanagihara's unweighted grading system increased from 13 to 31. We also discovered that the movement of the left eye was improved by 9-gaze photography. Our findings suggest that Korean medicine treatment has potential effects on esotropia and facial palsy caused by a pontine hemorrhage with a cavernous malformation.

  • Objectives: The purpose of this study is to investigate the characteristics, validity, and reliability of non-radiological assessment tools of scoliosis that have been studied so far. Methods: Electronic databases including Pubmed, Cochrane Library, CNKI, Science On, RISS, OASIS were searched by keywords including 'scoliosis assessment', 'scoliosis screening', 'physical examination', 'functional measurement', 'photography', and 'smartphone'. Results: 32 articles using radiation-free assessments were identified from 1,011 records. The mostly used non-radiological methods were Surface topography, Scoliometer, Ultrasound, Digital Infrared Thermal Imaging, and Photography. The other methods were Gait analysis, 3D depth sensor imaging, and Low intensity electromagnetic scan. Conclusions: It was found that non-radiological assessment tools might reduce the number of radiographs taken in scoliosis patients. To increase the reliability and validity, further research on the measurement tools of scoliosis will be needed.

  • In this study fashion illustrations published in American Vogue from 1960 to 1989 were investigated. Among the large number of illustrations published in American Vogue in this period a considerable number of illustrations was chosen: from 1960 to 1969 143 editorial illustrations and 333 advertisement illustrations; from 1970 to 1979 34 editorial illustrations and 168 advertisement illustrations; from 1980 to 1989 123 editorial illustrations and 81 advertisement illustrations. In studying those illustrations the main point was put in finding characteristics and the changing trend of fashion Illustrations. In the sixties editorial fashion illustrations were published mainly during early sixties. The Illustrations of Rene Bouch, Evelyn Marcil, Dagmar and Eunice Moore Sloane took the space of editorials. Among those Illustrators Bouch published most frequently. The companies such as Galey & Lord, Lord & Taylor, Bergdorf Goodman, Bonwit Teller etc. used fashion illustrations for the advertisement. The name Kenneth Paul Block, Babara Pearlman and Dorothy Hood can be found very frequently on the illustrations for those companies. Antonio Lopez too published in 1963 some advertisement illustrations. In the seventies the total number of editorial fashion illustrations diminished drastically compared to the number in the sixties. Antonio published in 1973 and 74 fifteen illustrations, Joe Eula published from 1976 to 79 thirteen illustrations, and beside them Mats Gustavson published in 1978 six illustrations. The number of advertisement illustrations decreased a little, but many companies used fashion illustrations for the advertisement. The illustrator who worked most actively were Block and Fred Greenhill. In the eighties editorial illustrations experienced a "Renaissance". New high-level illustrators appeared and new fashion illustration magazines were found. Antonio played a central role among illustrators published for editorials in Vogue. In addition to him 15 other illustrators including Mats and Eula with various styles worked for editorials. In contrast to the flourishment of editorial illustrations the number of advertisement illustrations decreased compared to seventies as a result of the domination of fashion photography in this area. Today only few fashion illustrations can be found in fashion magazines. The magazines are dominated by fashion photographs. However fashion illustrations will not totally perish from fashion magazines, because it still has some valuable functions in fashion advertisement. Those functions cannot be fulfilled by photography. Therefore fashion illustration will survive in fashion magazine but playa minor role compared to photography.

  • The wall painting of Altamira cave "eight-legged wild boar" is often presented as a typical example of long-held desire of humanity for expressing movement. However, the eight legs are the product of so-called "double layer", of two paintings painted in different periods. Nonetheless, the explanation of Altamira cave paintings linking with the origin of animation is constantly reproduced without any particular doubt, verification or citation of sources. The fact of associating eight legs with movement is irrelevant to visual perception transcending time. This should be considered a movement expression code invented in a particular period of time. Sequential photography tried in the late 19th century, in particular, chronography of $\acute{E}tienne$-Jules Marey plays a crucial role in this. Marey's photography of which a series of sequence movements are overlapped in one frame and printed was reflected in painting works of artists including Duchamp and Balla in the early 20th century and formed as movement expression code. Animation manuals started to emerge from that period of time introduced the images of Marey's chronophotography as a way of analyzing and embodying the movement. In sum, the act of considering Altamira cave paintings of eight-legged wild boar as an expression of movement is an error intending to look at the past through today's visual code.
