Objectives: We recently experienced one case of Transverse Myelitis. We would introduce the clinical report it Methods: In the point of Differentiation of Syndrome, these subjects were diagnosed as Wejeung(Weizheng;?證). We treated here with acupuncture. moxa, physical theraphy and herbal medication Results & Conclusions: Symptoms of the patient of this report were improved after above treatment. So it is suggested that oriental medical treatment is effective in Transverse Myelitis

Bordeaux mixture made with each grade of lime and copper sulfate was tested general property and disease control value. Bordeaux mixture was made by composition of each grade of lime (95%, 80%) with each grade of copper sulfate(98.5%, 95%). Phytotoxicity was evaluated to Bordeaux mixture made with each grade of lime and copper sulfate, and then low grade copper sulfate (95%) was more severely in the grapevine leaf. Bordeaux mixture, made with each grade lime and copper sulfate, were tried to evaluate control effects of downy mildew in field. As a result, Bordeaux mixture (95% of lime and 98.5% of copper sulfate, 6-6) applied 5 times at late in June was showed more effective disease control value than any other trials of Bordeaux mixture. There was no difference in nutrient status of petiole each treatment. But fruit characteristics were shown more slightly improved quality.

Objective : We used herbal medicine to treat various disease and also to keep good general condition of children. We aimed to evaluate the effect of herbal medicine on the growth of children treated with herbal medicine. Method: We studied 187 children who visited the department of Pediatrics, KyungHee Oriental Medical Hospital from March 2004 to August 2004. They meet condition as follows; they were treated for more than 6 months and they visited our clinic more than 3 times. Whenever patients visited our hospital, we measured their height, body weight and obesity degree using DS-102(dszenix, Seoul). We measured height percentile of first time visit, and that of last time visit. And we compared them using the Growth Statistics Curve made by the Korean Association of Pediatrics, 1998. Results : The mean growth of total children showed 4.04 percentile upwardly; the growth- up percentile of boys was 4.52 and that of girls was 3.26. Analysis according to disease resulted as follows; children with respiratory disease showed 10.29 percentile growth-up, digestive disease 4.21percentile, urinary disease 4 percentile, allergic disease 2.65 percentile, weak children 2.52 percentile and other disease 3.19 percentile. Conclusion : Herbal medical treatment helped growth not only in children who took medicine for growth retardation problem but children with various disease. Moreover herbal medical treatment applied to keep good general condition of children also gave positive effect on the growth of children.

Purpose: Although surgical resection is the most effective treatment for hepatocellular carcinoma (HCC) accompanied by portal vein tumor thrombus (PVTT), the recurrence rate is very high and prognosis is poor. This retrospective analysis aimed to establish a surgical strategy for patients with portal vein thrombus and to identify predictors of tumor thrombus in these patients. Methods: From 2006 to 2007, 63 hepatocellular carcinoma patients with portal vein thrombus detected by preoperative imaging underwent hepatic resection, and their clinical data were retrospectively analyzed. Possible prognostic factors for survival were analyzed with postoperative survival curves, and significant factors were determined by univariate and multivariate analysis. Results: 31 patients (49.2%) with portal vein tumor thrombus were detected by pathologic reports in 63 HCC patients with portal vein thrombus. Significant prognostic factors included Serum Albumin ≤3.5 g/dl, Alkaline phosphatase (ALP)≥100 IU/L, Tumor size≥10 cm, non-expanding type, PVTT and Alpha-feto protein (AFP)≥104 IU/L by univariate analysis. Independent prognostic factors included PVTT. Conclusion: PVTT is not always detected in patients with HCC accompanied by portal vein thrombus. Although patients have a portal vein tumor thrombus, some patients have greater long-term survival. Hepatic resection should be considered for patients with portal vein thrombus.

방위사업청에서는 무기체계 양산계약 체결 시 적정 원가를 산정하기 위해 방산원가대상물자의 원가계산에 관한 규칙과 시행세칙을 적용하고 있다. 방산원가는 크게 재료비, 노무비, 경비, 일반관리비, 이윤으로 구성되어 있으며 실제 발생한 비용을 원가로 인정하는 것을 대원칙으로 하고 있다. 이런 점은 업체로 하여금 비용절감에 대한 동기부여를 줄 수 없어 개선이 필요하다. 또한 계약 시점에 정해진 양산단가를 전체 계약기간에 동일하게 적용하는 방식은 비용절감 측면에서 부정적 영향을 줄 수 있어 보완이 필요하겠다. 본 연구에서는 이러한 부분을 개선하기 위해 원가자료의 신뢰도, 원가자료의 복잡도 등을 고려한 4가지 방법(업체제시 계산가격에 예가율 적용, 업체제시 계산가격에 조정률 적용, 원가항목별 조정률 적용, 원가항목별 조정률 및 학습률 적용)으로 양산단가를 추정하였으며, 분석결과를 바탕으로 최적의 방안을 제시하였다. 특히, 확률분포를 활용한 양산단가 추정을 위해 본 연구에서는 몬테카를로 시뮬레이션 기법을 활용하였으며, 연구 결과는 향후 무기체계 양산단가 추정의 신뢰도 향상에 기여할 수 있을 것으로 판단된다. In order to properly calculate the prime cost of a defense products, DAPA uses regulations and detailed rules on the calcuclation of a defense products upon arranging weapon systems contract for mass production. The prime cost is composed of material cost, labor cost, expenses, general administrative expenses and profits. The main principal is to disclose actual cost. This principal needs to be improved due to the fact that it does not steer contractors to lower productive cost. Also, this method can have negative effect on price reduction process in a whole contract period perspective. To overcome the mentioned problems, this study estimates the prime cost of mass production in consideration with cost reliability and complexity using four approach(Application of expectation rates on quotation, Application of mediation rates on quotation, Application of mediation rates on cost items, Application of mediation rates and learning rates on cost items) and proposes a most effective method based on analysis results. Especially, this research uses Monte Carlo simulation to estimate mass production. The results in this study will contribute in improving the reliability of cost estimation on defense mass production contracts in the future.

센서 네트워크는 센싱 기능과 데이터 처리 그리고 무선 통신기능을 갖춘 많은 노드로 이루어져 있다. 센서 노드는 제한적인 CPU, 배터리 그리고 저장공간과 같은 제약사항을 가지고 있기 때문에 시간이 지날수록 노드의 수명이 다해 전체적인 네트워크의 성능은 감소하게 된다. 본 논문에서는 이기종 센서 네트워크에서 노드 개수에 따른 작업 수행 시간의 분석을 통해 센서 네트워크의 수명을 판단한다. 성능 평가 결과 계층 기반의 라우팅 기법의 경우 클러스터 수의 비율이 네트워크의 수명에 큰 영향을 주는 것을 알 수 있다.
