Hemifacial microsomia is a common congenital craniofacial deformity involving bone and soft-tissue. Mandibular hypoplasia is the most obvious skeletal manifestation of hemifacial microsomia. In the past, complete realignment of the skeleton was preferred to soft-tissue correction, which was clearly second choice. However, in this study, simultaneous correction of bone and soft tissue deformities were equally important in treatment of hemifacial microsomia. One-stage and simultaneous bone and soft tissue reconstruction is possible and staged operations of the skeleton and soft tissue are no longer necessary, except in special cases. Even in children and adolescents, good results and normal growth potential can be achieved with simultaneous correction of bone and soft tissue.

The current studies investigated the therapeutic effects of Ephedra sinica Stapf (ES) herb-acupuncture on the inflammatory responses of rat arthritic joint, which was induced by the intradermal injection of heat-killed Mycobacterium tuberculosis emulsified in squalene to the base of the tail. The measurements of body weight and articular index were exploited as the assessment methods addressing arthritic symptoms, and the expression profiles of cytokines such as TNF-α, IL-1β and IL-6 in the, rat joint were analyzed using RT-PCR. The articular indexes of arthritic rats were significantly restored after the treatment with ES herb-acupuncture. Although the clinical symptoms of arthritic rats were apparently alleviated by the ES treatments, their body weights were not recovered. It maybe due to the weight-loss and energy enhancement effects of ES extracts. The expression of TNF-α, IL-1β and IL-6 enes, which were highly stimulated in the knee joints of arthritic rats, were restored to the levels of normal rats after the ES treatment. The therapeutic effect of ES herb-acupuncture was not observed in ES-treated, non-acupoint arthritic group as a sham control. The ES herb-acupuncture into an acupoint ST36 was found to be effective in alleviating the arthritic symptoms in adjuvant-induced arthritis rats as regards the body weight, joint appearance and the expression profiles of inflammatory cytokines.

In this paper, we propose a flexible turbo decoding algorithm for a high order modulation scheme that uses a standard half-rate turbo decoder designed for binary quadrature phase-shift keying (B/QPSK) modulation. A transformation applied to the incoming I-channel and Qchannel symbols allows the use of an off-the-shelf B/QPSK turbo decoder without any modifications. Iterative codes such as turbo codes process the received symbols recursively to improve performance. As the number of iterations increases, the execution time and power consumption also increase. The proposed algorithm reduces the latency and power consumption by combination of the radix-4, dual-path processing, parallel decoding, and early-stop algorithms. We implement the proposed scheme on a field-programmable gate array and compare its decoding speed with that of a conventional decoder. The results show that the proposed flexible decoding algorithm is 6.4 times faster than the conventional scheme.

1995년 4월부터 10월까지 전남 가막만과 경남 남해 해역에서 양식하는 조피볼락에 기생하는 아가미흡충 Microcotyle sebastisci의 기생률 변동 및 병리조직학적 변화를 조사하였다. M. sebastisci는 6∼7월에 나타나지 않았고, 주로 새엽 II∼III에 기생하였다. 기생된 부위는 미세한 출혈과 함께 점액이 다량 분비되었다. 남해의 경우 9월에 있어서 감염률, 상대 감염밀도, 평균 감염강도는 각각 40.0%, 30.7, 76.8을 나타내었다. 또한 가막만의 경우는 10월에 감염률, 상대 감염밀도, 평균 감염강도는 각각 46.0%, 40.5, 88.0으로 조사기간 중 가장 높게 나타났다. 병리조직학적 소견으로는 호흡상피세포의 증생, 비후, 새박판간상피세포의 중생과 새변의 곤봉화가 일어났다. 2차적으로 세균의 감염에 의한 아가미 부식도 관찰되었다. We report on the variation of infection and histopathological change of Microcotyle sebastisci parasitic on cultured rockfish, Sebastes schlegeli, in Namhae Islands and Kamak Bay from April to October in 1995. Microcotylosis due to Microcotyle sebastisci occurred among cultured rockfish, Sebastes schlegeli. This parasite was not found on the host fish from June to July. Parasite sites were mainly consist of 2nd and 3rd gill arch's filaments of rockfish. Also, the sites were secreted in large quantity of mucus with a very small bleeding. In Namhae Islands, maximum values of prevalence, relative density and mean intensity were found on September 1995, as 40.0%, 30.7 and 76.8, respectively. In Kamak Bay, maximum values of prevalence, relative density and mean intensity were obtained on October 1995, as 46.0%, 40.5 and 88.0, respectively. Histopathological changes of the heavily infested gills were showed necrosis, epithelium of the gill filaments underwent hyperplasia with fusion of the lamella and filamental clubbing. And a bacterial colony is invaded on the surface of lamella epithelium.
