  • The present study was designed to determine the effect of HCG administration to pregnant rats on the dam and its fetus including the corpora lutea, the body weight of the fetus, the resorption of the fetus and the malformations of the fetus in skeletal development when a single dose of HCG 50 IU or 100IU on day 4.8.12 or 16 of pregnancy. The results were summarized as follows: 1. Administration of HCG had no effect on the corpora lutea. 2. Fetal resorption was observed in animals treated with HCG on days 4.8 or 12, high incidence being treated with HCG on day 4 of pregnancy. 3. Administration of HCG had no effect on the weight of the fetus except decreasing in it treated with HCG on day 4 of pregnancy. 4. Administration of HCG might be able to induce the skeletal variations but was not the skeletal malformations and abnormal ossification of the fetus. The extra 14 ribs was observed in animals treated with HCG on days 8 and 16 of pregnancy, respectively. 5. It is suggested that HCG administration to pregnant rats was able to induce the fetal resorption and might be able to induce skeletal variations in the fetus.

  • In the medical image application the difference of intensity is widely used for the image segmentation and feature extraction, and a well known method is the threshold technique that determines a threshold value and generates a binary image based on the threshold. A frequently-used threshold technique is the Otsu algorithm that provides efficient processing and effective selection criterion for choosing the threshold value. However, we cannot get good segmentation results by applying the Otsu algorithm to chest X-ray images. It is because there are various organic structures around lung regions such as ribs and blood vessels, causing unclear distribution of intensity levels. To overcome the ambiguity, we propose in this paper an effective algorithm to extract pulmonary regions that utilizes the Otsu algorithm after removing the background of an X-ray image, constructs intensity-level maps, and uses them for segmenting the X-ray image. To verify the effectiveness of our method, we compared it with the existing 1-dimensional and 2-dimensional Otsu algorithms, and also the results by expert's naked eyes. The experimental result showed that our method achieved the more accurate extraction of pulmonary regions compared to the Otsu methods and showed the similar result as the naked eye's one.

  • In general, the H-shaped steel ribs or triangular lattice girders have been mostly used in constructing tunnels through the NATM construction method. The H-shaped steel rib has higher flexural and axial strength than the triangular lattice girder, but many unexpected gaps can occur in the concrete lining system after shotcreting if the H-shaped steel rib is used as the support system. To achieve better shotcreting quality, the triangular lattice girder was developed. However, in general, the triangle lattice girder has low flexural and axial strength. Likewise, the triangular lattice girder, which has circular sectional members, has so many fractures from welded points at the joints between the members. Finally, the new type of tetragonal lattice girder was developed to overcome those problems. In this study, the structural performance of the tetragonal lattice girders was evaluated through analytical and experimental studies. In the analytical studies, the four-point bending analysis, the traditional evaluation method to determine the flexural strength of the lattice girder, was performed. Moreover, the linear-elastic analysis and stability analysis of the arch structure made by the lattice girders were performed to measure structural performance. Experiments were likewise performed to compare the structural performances of the tetragonal girder with traditional triangular lattice girders.

  • The experiments was undertaken to evaluate the effects of herbal medicine, Dalsaengtang, in pregnant rats and fetuses. Female Sprague-Dawley rats were orally administered with the Dalsaengtang at dose of 5 mg/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and observed internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Maternal body weight of dalsaengtang treated group has a tendency to increase compared to that of control group. The relative liver and kidney weights of dalsaengtang treated group were also increased to that of control group. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and implantation rate, delivery rate, late resorption rate and sex ratio. But Dalsaengtang administered group showed lower early resorption rate than the control group. From the sex ratio, number of females, bigger than number of males in the control group, and more males than females in Dalsaengtang administered group. Neonatal body weight and number of fetus of Dalsaengtang group were increased to that of control group. The fetuses of dams treated with Dalsaengtang didn't showed external malformation. Vertebral and sternal variations were observed in Dalsaengtang group but, compared to the control, those variations were insignificant. The number of ribs, cervical, thoracic, and lumber were normal. The number of sacral and caudal vertebrae were increased. Fetuses showed significant difference in the number of caudal vertebra (P<0.01). From these results, it can be concluded that Dalsaengtang showed no toxicity effects on maternal body weight, early resorption rate, and number of live fetuses. There were no significant changes in organ weight, hematological data, reproductive organs. Although skeletal variations were showed in vertebrate and sternum, Dalsaengtang did not shown significant changes in bone malformation.

  • The study of bond behavior between concrete and rebar has been performed for a long time. On this study, we tried to analysed variation of bond behaviors quantitatively with varying the strength of concrete. Bond stress which observed below the neutral surface of beam and at connecting part of beam and column is affected by various bond parameters. Resistance of deformed bars which embedded in concrete to the pullout force is divided 1) chemical adhesive force 2) frictional force 3) mechanical resistance of ribs to the concrete and these horizontal components of resistance is being bond strength. We selected the most common and typical variable which is concrete strength among various variables. So we used two kinds of concrete strength like as 25MPa(NSC) and 65MPa(HSC). Tension Test was performed to verify how bond behavior varied with two kinds of concrete strength. Concentration of bond stress was observed at load-end commonly in Tension Test of the initial load stage. At this stage stress distribution was almost coincident at each strength. As tension load added, this stress distribution had difference gradually and movement of pick point of bond stress to free-end and central section was observed. This tendency was observed at first and moving speed was more fast in NSC. At the preceeding result the reason of this phenomenon is considered to discretion of chemical adhesion and local failure of concrete around rebar in load-end direction. Especially, when concrete strength was increased 2.6 times in tension test, ultimate bond strength was increased 1.45 times. In most recent used building codes, bond strength is proportioned to sqare root of concrete compressive strength but comparison of normalized ultimate bond strength was considered that the higher concrete strength is, the lower safety factor of bond strength is in each strength if we use existing building codes. In Tension Test, in case of initial tensile force state, steel tensile stress of central cross section is not different greatly at each strength but tensile force increasing, that of central cross section in NSC was increased remarkably. Namely, tensile force which was shared in concrete in HSC was far greater than that of concrete in NSC at central section.

  • This study was conducted to develop low-sodium Korean food recipes and evaluate consumer acceptability of low-sodium Korean food. A total of 137 consumers assessed the overall acceptability based on a 9-point scale. Statistical analyses were performed using the SPSS package program (ver 20.0). The results of this study are summarized as follows: According to the results of the consumer preference evaluation of low-sodium Korean food, overall acceptability of all menus was over five out of nine points (overall average 6.25). Overall acceptability was highest for grilled beef ribs (7.88), followed by bulgogi (7.63), sauteed dry anchovy (7.46), and simmered beef in soy sauce (7.45). On the other hand, overall acceptability was lowest in blanched and seasoned spinach (5.04). According to the results of Pearson's correlation analysis, overall acceptability was positively related with menu preference of 27 menus, including seasoned and simmered chicken (P<0.001), fiddledhead namul (P<0.001), and grazed lotus roots and burdock (P<0.001). To sum up, overall acceptability of all items used in the consumer preference evaluation was more than five points out of nine. Therefore, low-sodium recipe for Korean food can be effectively applied in commercial or non-commercial foodservice cafeterias.

  • Background: In malignancies, detection of metastatic foci is of value in making therapeutic plans for treatment of disease and prevention of life-threatening complications. Common sites for metastasis of bronchogenic cancer include lymph nodes, liver, brain, adrenals and bone. Skull, vertebrae, ribs and long bones are common sites for bone metastasis. But in epidermoid carcinoma, the incidence of bone metastasis is relatively low and especially to the distal phalangeal bone is rare. Methods: We experienced a case of epidermoid carcinoma with the first distant metastasis to the fifth distal phalangeal bone, right toe. Results: The initial stage in the diagnosis of epidermoid carcinoma was T4N3MO. During the third round of anticancer chemotherapy, we recognized the distant metastasis to the fifth distal phalangeal bone for the first time. Localized abnormal findings were noted by bone X-ray and scanning. By a histopathologic examination of the amputated toe, we confirmed the metastasis of epidrmoid bronchogenic carcinoma. Conclusion: If localized abnormal finding is discovered at an unusual site for metastasis, we recommend physicians to consider the possibility of metastasis even though it is very low.

  • Sternocostoclavicular hyperostosis is an uncommon disease, characterized by an inflammatory arthrosteitis of the sternocostoclavicular region. Clinically, it manifests as a painful swelling of the upper anterior chest wall, which is associated with occasional pustulosis palmaris and plantaris. A 48-year-old man had suffered from pain in both shoulders and the upper anterior part of the chest for 6 months. On examination, a venous engorgement in the neck with dilated collateral veins in the upper chest and shoulders was observed. Swelling was noticed in his face, neck and both arms. Radiologically, the clavicles, the sternum and the first ribs were enlarged with complete fusion between them. 99Tc scintigraphy showed increased uptake in the clavicles and the sternum. Selective venography resulted in a bilateral subclavian and brachiocephalic vein occlusion, which resulted from a subclavian vein thrombosis. All the above suggested a sternocostoclavicular hyperostosis. He underwent a vascular graft interposition between the right jugular vein and the left innomianate vein (using 8mm ringed Gore-Tex graft) and a resection of the bilateral medial half of clavicle and 1st rib. Here, we present a case on sternoclavicular hyperostosis with subclavian and brachiocephalic vein thrombosis, and report this case study with a review of the appropriate literature.
