  • Gelatin is a high molecular weight polypeptide derived fro mcollgen, theprimary protein component of animal connective tissues, which include bone, skin and tendon. Gelatin is usually produced from two different sources of raw materials (skins or bones) which are processed in two ways(line or acid). According to this pretreatment, gelatin can be divided into elatin type A(acid) and B(lime). The market is essentially driven by thre demand sectors: food, harmaceuticals(capsules) and photography. Although there is some potential threat in the photography sector, the oher tow sectors are well placed for futher growth.

  • Purpose: Direct anthropometry is an ideal method for preoperative planning and postoperative evaluation in plastic surgery, but it requires highly skilled specialty. Indirect anthropometry, especially photogrammetry, is an alternative method. In photogrammetry, standardized clinical photography is essential. Photogrammetry-based standardized clinical photography has several advantages over direct anthropometry. It is easier to measure and has less chance to make errors during measurement. Furthermore, it is possible to repeat measurements, and available for follow up study based on permanent custody. But, it is still different from actual measurement, and inherently less accurate than anthropometry. Methods: The authors revised the standardized clinical photography and then, carried out photogrammetry using Photoshop(Adobe, U.S.A.), and compared each data with those of anthropometry. The subjects were 50 males and 50 females, undergraduate medical students in twenties. Standard head position was obtained from the wire, fixed to cephalostat which indicates the Frankfort horizontal plane. All photographs were taken at the same situation such as fixed position of light, subject and camera, etc. Results: Total 96 measurements, based on 40 landmarks, consist of linear measurements, angular measurements and inclinations include 3 measurements in head, 22 in face, 15 in orbit, 28 in nose, 16 in lip and mouth, and 12 in ear. Conclusion: Normal photogrammetric data of face of Korean in twenties was obtained. Reliable photogrammetric measurements, not significantly different from anthropometric measurement statistically, accounted for 44 in 96 measurements(45.8%). Anthropometric values different from those of photogrammetric values were obtained by multiplying coefficient by photogrammetric value.

  • Underwater archaeology relies heavily on photography and video image recording during surveillances and excavations like ordinary archaeological studies on land. All underwater images suffer poor image quality and distortions due to poor visibility, low contrast and blur, caused by differences in refractive indices of water and air, properties of selected lenses and shapes of viewports. In the Yellow Sea (between mainland China and the Korean peninsula), the visibility underwater is far less than 1 m, typically in the range of 30 cm to 50 cm, on even a clear day, due to very high turbidity. For photographing 1 m x 1 m grids underwater, a very wide view angle (180°) fisheye lens with an 8 mm focal length is intentionally used despite unwanted severe barrel-shaped image distortion, even with a dome port camera housing. It is very difficult to map wide underwater archaeological excavation sites by combining severely distorted images. Development of practical compensation methods for distorted underwater images acquired through the fisheye lens is strongly desired. In this study, the source of image distortion in underwater photography is investigated. We have identified the source of image distortion as the mismatching, in optical axis and focal points, between dome port housing and fisheye lens. A practical image distortion compensation method, using customized image processing software, was explored and verified using archived underwater excavation images for effectiveness in underwater archaeological applications. To minimize unusable area due to severe distortion after distortion compensation, practical underwater photography guidelines are suggested.

  • This study was carried out to investigate the wearing silhouette of jackets according to the mechanical properties, primary hand value and total hand value of the 3 types of wool fabrics. Wool/PET(50/50), wool/PET(80/50) and wool(100%) fabrics were used as test specimens. Mechanical properties of specimens were measured by KES-FB system and primary hand value and total hand value were calculated by equation KN-203-LDY. We made three experimental jackets based on the precious jacket pattern and used Moir Photography to measure the amounts of space between the jacket clothes and body surface from the overlap cross section map. The results were as follows: 1) In mechanical properties, woo/PET(80/20) fabric showed higher bending and shear rigidity. 2) In evaluation of primary hand and total hand, wool 100% fabric showed higher NUMERI and FUKURAMI hand and total hand value. 3) From the reset of Moir Photography, the wearing shapes of the experimental jackets were influenced by the characteristics of fabrics. Except for the hip part, the garment ease of wool/PET(80/20) fabric was estimated more highly.

  • The surface change of upperarm and shoulder blade area are caused by the extensive upper limb movement, thus it is necessary to measure the amount of change for constructing the clothing. Moire photography was taken after plastic casters of upperarm and shoulder blade area was prepared. 1. For the shoulder blade area, subjects showed the same change of surface area for the various limb positions, wherease, for the upperarm only at the $0^{\circ}\;and\;180^{\circ}$ limb position, same change was observed. 2. As the movement of the upperarm was increased, surface area of axillary part was increased and that of shoulder part was decreased. 3. To make a bodice pattern, the minimum size of the back with the ease were $\frac{B}{4}$+3.13 cm R for normal wear and $\frac{B}{4}$+5.75 cm for active wear. 4. As the movement of the arm was increased, the cross section for the upperarm were changed to elliptical shape. 5. For each horizontal basic line, there was a positive correlation between the amount of change of shoulder blad area and that of upperarm area.

  • The consumption became a virtue of social in 20th century, and this consumption culture created an ideal body image through mass media. Sexual image became a new standard of 'beauty' in a modern fashion, and designs which expressed sexual image appear every season. Individuals were fascinated with some parts of human body. These body parts are different based on the time period and the culture that the individual belonged to. This study focused on the erotic body parts and expression on the editorial fashion photography. Eroticism represented in the editorial fashion photographs can be divided into the expression by clothing design and by creating erotic atmospheres. Erotic expressions by clothing design can be presented by 1)exposing directly 2)exposing indirectly 3)emphasizing the body parts. The most frequently presented erotic body parts in fashion photographs were legs(25%), followed by the bodice with breast (21%), the waist (16%), the hip (12%), neck & shoulder (10%), arms (9%), and abdomen (7%). The results indicated that legs were considered to be a erotic body parts often than the traditionally referred erotic body parts, such as bodice with breast or hip. While direct exposing method (e.g., adhesion, see-though) was frequently used for other body parts.
