In this paper, we have proposed new solution methods to solve TSLP (two-stage stochastic linear programming) problems. One solution method is to combine the analytic center concept with Benders' decomposition strategy to solve TSLP problems. Another method is to apply an idea proposed by Geoffrion and Graves to modify the L-shaped algorithm and the analytic center algorithm. We have compared the numerical performance of the proposed algorithms to that of the existing algorithm, the L-shaped algorithm. To effectively compare those algorithms, we have had computational experiments for seven test problems.

Antithymocyte globulin (ATG) is used as an immunosuppressive treatment (IST) to deplete clonal suppressor T cells in patients with severe aplastic anemia (SAA). The depletion of suppressor T cells by ATG may affect the activation of B cells, which results in an increased risk for autoimmune conditions. A 12-year-old boy was diagnosed with idiopathic SAA. As he did not have an human leukocyte antigen-matched sibling, he was treated with rabbit ATG (3.5 mg/kg/day for 5 days) and cyclosporine. Five months later, he became transfusion independent. However, 23 months after IST, he complained of mild hand tremors, sweating, weight loss, palpitations, and goiter. Results of thyroid function tests revealed hyperthyroidism (free thyroxine, 3.42 ng/dL; thyroid stimulating hormone [TSH], <0.01 nIU/mL; triiodothyronine, 3.99 ng/mL). Results of tests for autoantibodies were positive for the antimicrosome antibody and TSH-binding inhibitory immunoglobulin, but negative for the antithyroglobulin antibody and antinuclear antibody. He was treated with methimazole, and his symptoms improved. The patient has been disease free for 39 months after IST and 9 months after methimazole treatment. This case report suggests that although rare, rabbit ATG may have implications in the pathogenesis of autoimmune hyperthyroidism. Our findings suggest that thyroid function tests should be incorporated in the routine follow-up of SAA patients treated with ATG.

Propylthiouracil (PTU) is one of the most common drugs used in the treatment of Graves' disease. There are a number of side effects found with PTU use including fever, rash, arthralgia, and flu-like symptoms. Recently antineutrophil cytoplasmic antibodies (ANCA) positive vasculitis after PTU treatment was reported as a rare side effect, which can cause diffuse alveolar hemorrhage and glomerulonephritis. A 45-year-old woman with Graves' disease had been treated with PTU for five months, complained of hemoptysis due to pulmonary alveolar hemorrhage causing anemia, and also had hematuria. Simple chest X-ray and HRCT showed bilateral consolidation and bronchoalveolar lavage fluid revealed alveolar hemorrhage. A serologic test was positive for ANCA against myeloperoxidase and proteinase-3. Such findings suggested that the presence of PTU induced ANCA positive vasculitis. Cessation of PTU and the administration of high dose steroids improved the clinical manifestation, radiologic and serologic findings. We observed ANCA titer serially for 6 years. During the follow up period, ANCA titer decreased slowly and stayed within the acceptable upper normal limit.

Our previous research on coprolite specimens from the mummies of Joseon Dynasty (1392-1910 CE) has revealed various species of parasite eggs. Herein, we added 2 new helminthic cases of human remains from Joseon-period graves in the Republic of Korea (Korea). The organic materials precipitated on the hip bones of 2 half-mummied cases (Goryeong and Gwangmyeong cases) were collected, rehydrated, and examined by a microscope. In the sample from Goryeong-gun (gun=County), ova of Trichuris trichiura, Clonorchis sinensis, and Metagonimus spp. were detected, and eggs of T. trichiura and A. lumbricoides were found from the sample of Gwangmyeong-si (si=City). By adding this outcome to the existing data pool, we confirm our previous estimates of Joseon-period parasite infection rates. The overall rates of A. lumbricoides, T. trichiura, and C. sinensis decreased dramatically from Joseon to the modern period. In Goryeong mummy specimen, we also found Metagonimus spp. eggs that has rarely been detected in archaeological samples so far.

A Study on the construction of Chulik in the early 16th century based on the shrouds from the excavated grave of Kim, Heum-Jo(1461∼1528) is reported in this paper. This paper first reviews the general construction methodology found in the shrouds from other graves in early 16th century revealed from a report on Chulik from the excavated grave of Kim, Heumjo. This paper finds that there exist at least three different Chulik forms according to the ratios between upper portion and lower portion in Chulik. The upper portion to the lower portion ratio grows with time. Among the three forms, this Chulik of interest falls in the first one of the three forms. This new finding of the chronological evidence for the first category of the three forms provides us the latest chronology for the first category, which is up to the year 1567. This paper also shows that the second and the third categories of Chulik in early Chosun Dynasty lasted until 1580\`s and until 1590\`s, respectively. Several remarks on construction methodology found in the Chulik of interest are also reported in this paper.

Myasthenia gravis is a disorder of neuromuscular transmission which is characterized fatigue and weakness of the voluntary muscle. From 1985. 1 to 1991.6, 34 patients underwent managed including 12 patient thymectomy, at the kyunghee medical center. A clinical analysis was performed and following result was obtained. Among the 34 patients, male to female ratio was 11 : 23 and the age was ranged from 2 years to 63 years. Thymectomy was done in 12 case and 1 case of malignant thymoma was not resectable. There were 2 deaths after operation due to respiratory failure and 1 death dur to gradually progression. THe effect of thymectomy in mtasthenia graves was 66.7% (8cases). The prognostic factors were severity of the disease and histopathological findings. Others were not related to the prognosis of the mayasthenia gravis. The severity of the myasthenia gravis was classified by Osserman modified classification.

This study implicates that the Danryoung(Formal dress) has been worn by the lady in Joesun dynasty. So far 8 cases of Danryoung excavated has been supposed to be worn by woman. The differences between man and woman's Danryoung is at the 'Somae(sleeve)'and 'Mu(gusset)'. Through those excavated Danryoungs, 'Somae' in Woman's Danryoung was straight and 'Mu' attached in outer layer of dress with rectangular form. From the excavated dresses, Ot-go-reum(strings) coloured violet and wider than man's Danryoung. It was also found as detached. Woman's Danryoung was decorated with gold brocade and excavated with belt. Through the dress and accessories excavated, it was estimated in mid-16C to early 17C. With this respect, it was implicated that Danryoung has changed its style to Wonsam after late 17C.

In this study, Field-Programmable Gate Arrays (FPGAs) are investigated as a practical solution to the challenge of designing an optimal platform for implementing algorithms in a wireless sensing unit for structuralhealth monitoring. Inherent advantages, such as tremendous processing power, coupled with reconfigurable and flexible architecture render FPGAs a prime candidate for the processing core in an optimal wireless sensor unit, especially when handling Digital Signal Processing (DSP) and system identification algorithms. This paper presents an effort to create a proof-of-concept unit, wherein an off-the-shelf FPGA development board, available at a price comparable to a microprocessor development board, was adopted. Data processing functions, including windowing, Fast Fourier Transform (FFT), and peak detection, were implemented in the FPGA using a Matlab Simulink-based high-level abstraction tool rather than hardware descriptive language. Simulations and laboratory tests were carried out to validate the design.

This study investigates the chulik of Soo Buen's, Heymjo Kim's, Sooncheon Kim's grave in early Chosun Dynasty. The purpose of this study is to revise concretely the relation to Mongolian costume, Zilsun and Chulik, of the distintion of sex to wearer. This paper reviews the general construction form the excavated graves of them. This paper finds that there exist different Chulik forms according to the ratios between upper portion and lower portion in Early Chosun Dynasty. Eventhough they were a kind of Mongolian costume, in relation to Zilsun(質孫) and Chulik(帖 ) they are different form each other. They have a lot of pleats coat( 積袍), but they are different clothes, and also, even if Chulik were excavated in womens grave, because their husbands presented them to their wives, Chuliks were not women's, and they were used for men.
