  • Background and Objectives This study was conducted to gather three dimensional images from computed tomogram in detecting and gaining information about fish bones. Materials and Methods Thirty-nine fish bones and 2 chicken leg bones were used. Bones sandwiched between the cotton sheets were placed into the 3 plastic boxes. Computed tomogram of the bones in the boxes were reconstructed three-dimensionally by Xelis (Infinitt, Korea) to make images of MPR, MIP and VR images. The images were compared with real chicken bones and fish bones as to possibility of detection, finding of location and orientation, and evaluation of shape and calculation of size. Results All 41 bones were detected in all reconstructed images. Distance to the bones from reference point can be measured and orientation can be checked. Shapes were similar between matched images of all real bones. Conclusion The results indicate the usefulness of 3D reconstruction technique in getting informations about fish bones.

  • The effects of the water extract of beef shank bones on the physical and sensory characteristics of cooked rice for JeonJu Bibimbap were investigated. Five kinds of cooked rice were prepared with 0%(control), 20%, 40%, 60%, and 100% of the beef shank bones extract. An increase in the beef shank bones extract concentration was associated with a lower moisture content of the cooked rice. The color(L, b value) of the cooked rice prepared with the beef shank bones extract became gradually darker during storage at $60^{\circ}C$. In regards to the textural properties of the cooked rice, the hardness increased with the addition of the beef shank bones extract and chewiness was changed in a similar pattern to that of hardness. However, the adhesiveness significantly decreased. In the sensory evaluation, the cooked rice prepared with 20 and 40% of the beef shank bones extract had the best sensory quality for JeonJu Bibimbap.

  • In this study, the micro-FE analyses were carried out for the plastic behaviour of vertebral trabecular bones. Many researchers have investigated the elastic behaviour of trabecular bones by using the micro-finite element models based on the micro-CT images. However, there was no micro-FE model to account for the plastic behaviour of trabecular bones. Ulrich et at. reported that best results at coarser model were obtained when using 'compensated hexahedron models' with the same relative density. This study indicates that, for the elastic and plastic analysis, 'the compensated hexahedron FE model' is likely to be limited to about 63$\mu\textrm{m}$ image resolution in the vertebra trabecular bones.

  • We carry the knowledge that the skeleton bones of the human body are not always without defects and some various defects could occur in them. In the present paper, as the first endeavor, free vibration and buckling analysis of femur bones with femoral defects are investigated. A major strength of this study is the modeling of defects in femur bones. Materialise Mimics software is adopted to model the bone geometry and the SOLIDWORKS software is used to generate the defects in bones. Next, the ABAQUS software is employed to study the behaviors of bones with defects.

  • Animal bones that were excavated with earthenware at the Jongdal-ri shell mound archaeological site IV on Jeju Island were investigated morpholgically and osteometrically. This archaeological site is estimated to date from the late Tamra period to the unified Shilla Dynasty (A.D. 7C) based on the type of earthenware. The number of animal bones was 3,430 pieces(Quarter B : 758, Quarter C : 2,672). The animal species consisted of Cervus spp., Sus spp., Bos spp and Canivore. The animal bone pieces excavated at Quarter B consisted of those of Cervus(53.3%), Bos(2.8%) and Sus(13.7%). The bones of Cervus(53.3%), Bos(2.8%), Sus(13.7%) and Canivore(4.6%) were found at Quarter C. The greatest number of heads was unearthed as a whole, and the classification according to animal species showed that the heads were more visible than other bones. Forelimbs and hindlimbs were distributed evenly on the part of Cervus. The skeletons from Bos were identified in the order of heads, forelimbs and hindlimbs, while nearly all the Sus bones were found to be heads. These data suggests that Cervus, Sus and Bos are major fauna at the estimated period.

  • Animal bones excavated with earthenware from the shell mound at the Jeju Jongdali 1819 archeological site, where three consecutive chronological layers covering the Neolithic (B.C. 15C-B.C. 10C), early Tamra, and late Tamra periods have been identified, were morphologically classified. The majority of the bones from all three periods were broken or split. The major fauna of the mammalian bones in all periods were Cervus spp., Sus scrofa, and Bos taurus. In the early and late Tamra periods, bones of small animals including Mustela sibirica coreana, Meles meles, Rodentia, and Aves were also found in small number. The excavated bones were from all parts of the animal bodies, including head, trunk, forelimb, and hindlimb. Collectively, these findings suggest that the major fauna from the Neolithic to late Tamra periods consisted of Cervus spp., Sus scrofa, and Bos taurus and that the fauna was dissected and carried to the shell mound site after hunting. Information from the bone remains in the shell mound are useful data for study of the wildlife and domestic animals living during the prehistoric period of Jeju Island.

  • Most human bones of Joseon Dynasty period are so good condition that we can do research in physical anthropology, genetics and chemistry with them. In this study, we analyzed DNA typing using 6 human bones of Joseon dynasty period excavated at Janggi-dong, Gimpo. The DNA typing was mitochondrial DNA haplotype, Y-chromosome haplotype and sex determination. Prior to DNA analysis, we distinguished histological index of 6 human bones. As the result of mitochondrial DNA analysis, most of bones were confirmed as haplogroup G, R11, M7, A5, etc. As the result of sex determination, 4 human bones were female and 2 human bones were male. The male haplogroup was confirmed as haplogroup O by the single nucleotide polymorphism analysis of Y chromosome. For extensive ancient human bone analysis, researchers need to apply a histological index to select ancient human bones and explain a relationship among ancient human bones with various analyses of mitochondrial and nuclear DNA.

  • Fibrous dysplasia is a benign disorder of bone consisting of intramedullary proliferation of fibrous tissue and irregularly distributed, poorly developed bone. The disease manifests itself in the monostotic form in which only one bone is involved and the polyostotic form in which multiple bones at different sites are affected. We reported a extensive case of polyostotic fibrous dysplasia with involvement of craniofacial bones, mandible, ribs and extremities. A 18-year-old man showed remarkable right facial swelling who had been treated on right femur 3 years ago with a bone graft for pathologic fracture and he recognized facial swelling 5 years ago. Extraoral radiograms and computed tomogram showed diffuse sclerosis with a ground glass appearance of the most cranial bones, facial bones. The right mandibular lesion showed very expansile lesion with mottled appearance. Bone scans showed mutifocal increased uptakes in craniofacial bones, right mandible, bilaterally in ribs, humerus, femur, tibia and characteristic varus deformity of right femur (shepherd's crook defomity). This case showed exceptionally bilateral, extensive nature of bone lesion and didn't show any features of skin pigmentation and endocrine disturbances.

  • The abnormal female fowl (Arbor Acres broiler) of 40-day-old, which was polymelia with polydactyly was observed macroscopically and radiographically. An extra pelvic limb was attached at the left pelvic region. The extra pelvic limb consisted of an underdeveloped and malformed Os coxae like bone, femur like bone, tibia and fibula like bones, tarsal and metatarsal like bones, and five digits. The tarsal bones of two normal pelvic limbs and one extra pelvic limb were not fused with tibia and metatarsal bones respectively. The metatarsus of extra pelvic limb consisted of a single bone derived from several components. In a case of normal, first metatarsal bone remains independent. However in this case. all of metatarsal bones were fused. The extra pelvic limb was polydactyly. The digits consisted of the first and extra digit of three. the second and third of four. and the fourth of five phalanges. In each toe the last phalanx was pointed and formed the claw. The first and the second digits were polyphalangia [hyperphalangia]. The extra digit was microdactylia and brachydactyly.
