Due to the rapid growth of the online fashion market and the resulting expansion of online choices, there is a problem that the seller cannot directly respond to a large number of consumers individually, although consumers are increasingly demanding for more personalized recommendation services. Images are being tagged as a way to meet consumer's personalization needs, but when people tagging, tagging is very subjective for each person, and artificial intelligence tagging has very limited words and does not meet the needs of users. To solve this problem, we designed an algorithm that recognizes the shape, attribute, and emotional information of the product included in the image with AI, and codes this information to represent all the information that the image has with a combination of codes. Through this algorithm, it became possible by acquiring a variety of information possessed by the image in real time, such as the sensibility of the fashion image and the TPO information expressed by the fashion image, which was not possible until now. Based on this information, it is possible to go beyond the stage of analyzing the tastes of consumers and make hyper-personalized clothing recommendations that combine the tastes of consumers with information about trends and TPOs.

Background: The megakaryopoiesis and platelet production is regulated by several hematopoietc factors such as thrombopoietin (TPO), interleukin-11 (IL-11) and interleukin- 3 (IL-3). IL-11 is a potent stimulator of megakaryopoiesis in vivo, and acts primarily as a megakaryocyte maturation factor in vitro and it can act synergistically with IL-3 and TPO. We performed this study to investigate the effects of recombinant human IL-11 (rhIL-11) with other hematopoietic factors on megakaryocyte colony formation in vitro. Methods: CD34+ cells were separated from umbilical cord blood and megakaryocyte colonies using MegaCult Assay Kit were cultured with rhIL-11, recombinant human IL-3 (rhIL-3), and recombinant human TPO (rhTPO) for 7 and 14 days. The number and percentage of CD34+ and CD41a+ cells were determined by flowcytometry. Results: The number of CD41a+ cells were $0.54{\pm}0.05{\times}10^4$ (rhIL-11 100 ng/ml), $5.32{\pm}0.23{\times}10^4$ (rhIL-3 100 ng/ml), and $8.76{\pm}0.15{\times}10^4$ (rhTPO 50 ng/ml) of total expanded cells during the culture of the purified CD34+ cells in liquid phase for 7 days. The number of CD41a+ cells were increased to $7.47{\pm}0.69{\times}10^4$ (rhIL-3+ rhIL-11), $11.92{\pm}0.19{\times}10^4$ (rhTPO+rhIL-11) of total expanded cells, respectively, during the culture of the purified CD34+ cells in liquid phase for 7 days in the presence of rhIL-11 (100 ng/ml). When the purified CD34+ cells were cultured in semisolid mediaincluding various concentration of rhIL-11, the megakaryocyte colonies were not formed. When the purified CD34+ cells were cultured with rhIL-11 and rhTPO or with rhIL-11 and rhIL-3, the number of megakaryocyte colonies were increased compared with rhTPO or rhIL-3 alone. Conclusion: These results indicate that IL-11 exerts a potent proliferative activity to colony forming unit-megakaryocyte from human umbilical cord blood, and it acts with other hematopoietic factors synergistically.

The objective of this study was to evaluate tire effects of modified triple pelvic osteotomy(TPO). The procedures of modified TPO were composed of two iliac osteotomies and a pubic symphysiotomy at a tittle. Medical records of modified TPO treatment on 36 dogs and of unilateral TPO on 7 dogs were reviewed on the basis of signalment, body weight, operation time, Healing time of osteotomy sites and complications from October 2002 to September 2004. The values of clinical status and hip dysplasia, Norberg angle, percentage of femoral head coverage and pelvic diameter from radiographs taken preoperative, immediately postoperative, 2, 4, 8, 12 and 24 weeks after operation, respectively, were measured. In .unilateral TPO, the dogs could start standing without assistance from $3.0\pm1.0days$ and walking from $8.3\pm0.6days$ (n=3). Mean clinical grade before and 24 weeks after surgery were $2.2\pm0.42$(n=6) and $3.5\pm0.7$ (n=2), respectively. Mean operation time was $107.3\pm38.9$ minutes (n=4). In modified TPO, the dogs were seen to staff standing without assistance from $4.9\pm3.7$ days and walking from $7.3\pm4.8days$ (n=25). Mean clinical grade before surgery and 24 weeks after surgery were $2.3\pm1.5$ (n=27) and $3.2\pm0.7$)(n=9), respectively. Postoperative clinical grade significantly improved against preoperative clinical grade (P<0.01). Mean operation time was $143\pm42.8$ minutes (n=24). This was shorter than time f3r twice unilateral TPO. By comparison with preoperative values, postoperative mean radiographic grade, percentage of femoral head coverage and Norberg angle measured at the recheck time point significantly increased (P<0.01). Mean postoperative pelvic diameter was significantly larger than preoperative pelvic diameter in modified TPO (P<0.01) but not in unilateral TPO. These results indicated that modified TPO was effective technique for the treatment of hip dysplasia in dogs.

Objectives : Korean traditional medicinal herbs have been used to improve the function of the hematopoietic system. The purpose of this study is to examine the hematopoietic effects of Juakium-derivative on aplastic anemia. Methods : In vitro, after bone marrow cells of mice with aplastic anemia induced by benzene were cultured with Juakium-derivative, we measured the gene expressions of hematopoietic cytokines, the intracellular TPO and SCF expression and the colony number of CFU-GEMM and BFU-E. Results : The results are summarized as follows : 1. The gene expressions of hematopoietic cytokines (TPO, c-mpl, SCF, c-kit, IL-3, EPO, EpoR, GM-CSF) and the TPO and SCF expression of the group treated with Juakium-derivative increased significantly more than those of the control group. 2. The colony number of CFU-GEMM and BFU-E in the rEPO plus rIL-3 plus Juakium-derivative group increased significantly compared with the only rEPO plus rIL-3 group. Conclusion : It was acknowledged that Juakium-derivative has hemato-potentiating effects on aplastic anemia induced by benzene and it is expected that Juakium-derivative can be used clinically for the patient with hematopoietic system disorder. This study could also be used further as important research data for Korean oriental medicine about hemato-potentiating. The exact mechanism explaining our study would need to be studied further.

Purpose : This study analyzed the expression of HLA-DR and DQ genotypes and anti-thyroid autoantibodies[anti-thyroid peroxidase(TPO) and anti-thyroglobulin(TG) antibodies] in Korean patients with type 1 diabetes(T1DM) to investigate the susceptible HLA alleles to T1DM in Korea and the prevalence of thyroid autoantibodies and their significance for the development of thyroid disorders. Methods : A total of 59 Korean patients with type 1 diabetes[26 males, median age 13.7 years(range 5.7-29.9 years), diabetes duration 7.6 years(-1.7-22.5 years)] were enrolled in this study, and 200 healthy Koreans without a family history of diabetes were selected as a normal control for the comparison of HLA genotypes. Seventeen patients with anti-TPO or anti-TG were followed [median duration 3.96 years(1 day-10.7 years)] with measurement of anti-TPO, anti-TG, $T_3$, $T_4$ or free $T_4$, TSH levels and physical examinations. HLA-DR and DQ genotyping were done by PCR-SSO, PCR-SSCP, PCR-RFLP and PCR-SSP methods. Results : HLA analysis showed higher frequencies of HLA-DRB1*0301, *090102 and DQB1*0201, *030302 alleles, DRB1*0301/*090102, *090102/*090102 and DQB1 *0201/*030302, *030302/*030302, *0201/ *0302 genotypes in T1DM patients compared to controls(Pc<0.05). Fifteen(25.4 percent) had anti-TPO antibody, 12(20.3 percent) had anti-TG, 17(28.8 percent) had either autoantibody and 10(16.9 percent) had both autoantibodies. No clinical or subclinical hypothyroidism developed during follow-up after the first detection of anti-thyroid autoantibody. There was no significant correlation between thyroid autoimmunity and gender, onset age of T1DM, and diabetes duration, respectively(P>0.05). Conclusion : We thought this unique HLA-DR, DQ allele distribution might be an important factor for the low incidence of T1DM in Korea. And a high prevalence of thyroid autoantibodies in these populations suggests examinations of thyroid antibodies should be performed regularly. Optimal age for the initial screening and the frequency of re-screening for associated thyroid autoimmune diseases in T1DM remains to be determined through prospective follow-up.

Temperature programmed oxidation (TPO) is used to characterize coke species deposited on commercial nickel catalyst, C11-PR during propane pre-reforming. Propane pre-reforming performed under various condition, S/C from 1.5 to 2.5 and temperature from $350^{\circ}C$ to $450^{\circ}C$. There are three kinds of coke species detected by TPO: (i) reactive coke, (ii) coke deposited on metal site and (iii) coke deposited on acid support. Coke deposited on metal and support are minimized although reactive coke is generated at temperature of $400^{\circ}C$ and S/C of 2.0. Reactive coke is expected to remove easily below temperature of $200^{\circ}C$. Therefore, optimized pre-reforming condition for propane is $400^{\circ}C$ and S/C of 2.0.

Objectives : Korean traditional medicinal herbs and some formulas have been used to improve the function of the hematopoietic system. The present research is to examine the effect of DanSamSaMul- Tang(DSSMT) as a biological response modifier related to hemato-potentiating function using bone marrow cell as a testing system. Methods : Mice with leukopenia and thrombocytopenia induced by CTX were treated with DSSMT Extracts. Then we observed cytokines mRNA expression level, the number of CFU-GEMM and BFU-E, and the expression of TPO and SCF in bone marrow cells of mice. Results : In the DSSMT group, the gene expressions of hematopoietic cytokines were increased significantly and the number of CFU-GEMM and BFU-E of this group was significantly increased compared to the group treated only with EPO and IL-3. The expressions of TPO and SCF in the group treated with DSSMT were higher than those of the control group. Conclusions : We showed that DSSMT has a good effect on the hematopoietic system. This could also be used as important research data for Korean oriental medicine about hemato-potentiating.
