The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

양종현,임재복,정재영 광주대학교 1997 産業技術硏究 Vol.9 No.-

본 연구는 프랙탈 영상 압축[1]을 위한 효과적인 분할 방법을 제안한다. 먼저 원 영상을 일정한 작은 크기의 치역(Range Block)과 분할된 치역의 2배 이상 크기를 가진 정의역(Domain Block)으로 분할한다. 여기에서 정의역과 치역으로 구성된 분할 형태를 이용하는 프랙탈 영상 압축은 작은 사각 블록들의 집합으로 구성되어 진다[2]. 서로 연결된 사각 블록들의 집합은 프랙탈 부호를 가지는 이웃하는 분할(Partition)들로 연결되어 있으며, 이러한 블록들로부터 임의의 서로 이웃한 블록을 제외한 정의역 블록과 치역 블록을 적당한 기준에 의해서 선택한다. 선택된 블록은 다시 사각트리(quad tree) 분할 비교를 행함으로써 최적 분할에 접근이 인정될 수 있음을 보여준다. This paper introduces efficient partitionning methode in fractal image compression. Before, Original image is devide into regular size called the Range block and A domain block size is double of range block. Here domain and range block consist of a collection for small size partition using fractal image compression. Each connected sets of small square image blocks, of which is a neighbor partitioning with a fractal code. They are selected for which except random neighoboring domain and range block on a fitness criterion. This approach showed as compared to quad tree partition.

A classification algorithm of traffic signs using a MSHMT (modified synthetic hit-miss transform) is proposed for the autonomous road vehicles(ARV's). In the case of classification of traffic signs, there are many kinds of signs with intraclass distortions and interclass similarities. The MSHMT provides a good solution with the property of distortion invariant recognition of multiple objects in noisy and cluttered scene. The proposed algorithm of traffic sign classification consists of the phase of sign detection and the phase of symbol recognition. In the phase of sign detection. structuring elements(SEs) are synthesized using only set theory to adapt to simple variations. In the phase of symbol recognition, SEs are synthesized using set theory and SDFkynthetic discriminant function) synthesis method to adapt to complex variations. Based on extensive simulations, it has been shown that the proposed algorithm is efficient for the classification of traffic signs.

The natural convection driven by a thermal buoyancy force was investigated in a square cavity. The top and bottom walls are cold and hot, respectively, while the vertical boundaries are adiabatic. A control volume approach with a power-law scheme was used to formulate the finite difference equations. The results are presented isotherms, velocity vectors, Nusselt numbers and critical Rayleigh numbers for the ranges of Ra = 1750 ∼ 20000 and Pr = 0.05 ∼ 10.0. The critical Rayleigh number increases as Prandtl number decreases. There exists a clockwise unicell flow near critical Rayleigh number, while two cells appear for large Rayleigh number.

다단계 BTC에 대한 유전자 알고리즘 설계

양종현,김향태 광주대학교 1999 産業技術硏究 Vol.13 No.-

본 논문에서는 다단계 BTC 부호화의 설계에 대한 새로운 스키마를 제안한다. 최적의 양자화는 상세한 탐색으로 양자화 초기값을 선택함으로써 얻을 수 있다. 그러나, 이것은 거대한 양의 계산결과를 요구하고, 또한 다단계 BTC에 대한 상세한 탐색을 고려했을 때 비현실적이다. 원래의 이미지와 재구성된 이미지 사이의 AMSE(average mean square error)가 최소이기 위한 더 좋은 초기 값 유지하기 위해서 유전자 알고리즘을 적용한다. 상세한 탐색으로 제안된 방법의 결과치를 비교하면 전자의 방법이 대부분 후자의 경우에서 요구된 것 보다 훨씬 적은 계산량으로 적절한 양자화를 달성할 수 있다. In this paper, a new scheme for designing multilevel BTC coding is proposed. Optimal quantization can be obtained by selecting the quantization threshold with an exhaustive search. However, this requires an enormous amount computation and is, thus impractical when we consider an exhaustive search for the multilevel BTC. In order to find a better threshold so that the average mean square error between the original and reconstructed images is a minimum, the genetic algorithm is applied. Comparison of the results of the proposed method with the exhaustive search reveal that the former method can almost achieve optimal quantization with less computation than that required in the latter case.

This study focuses on the human rights and welfare of adolescents who are in the military service. An adolescent should have rights of care, autonomy and participate. In Korea, mandatory military service is required for men. Thus their rights can be violated in the military. In this study, the rights of adolescents were categorized as the right to live, protection, develop and care, and the ways of providing those rights in the military were discussed.

Membranous nephropathy (MN) is a glomerular disease characterized by diffuse thickening of the glomerular basement membrane without significant mesangial proliferative change and is usually manifested by the nephrotic syndrome. To evaluate the clinical and pathologic characteristics of this disease in adults, we analyzed 65 patients with primary membranous nephropathy who were diagnosed at Department of Internal Medicine, Chungnam National University Hospital from February 1986 to February 2001. The results are as follows: 1) Of total 96 patients with membranous nephropathy, 67.7% was primary MN. Hepatitis B-associated MN and lupus MN were 22.9%, and 9.4%, respectively. Median duration of follow-up was 35.1 months(0.3∼177) in primary MN, 49.6 months(2.5∼103) in lupus MN, and 35.6 months(0.5∼108) in hepatitis B-associated MN. 2) Mean age of the patients with primary MN at the time of diagnosis(43.3 years) was significantly higher than that of lupus MN(30.4 years) and HBV-associated MN(36.2 years). Male to female ratio of primary MN was 1.03:l. 3) At the time of diagnosis, 89.2% of primary MN was presented with nephrotic syndrome. Twenty seven percent of patients showed hypertension. Hematuria was found in 58.5% of primary MN patients. Azotemia was noted in 3.1 %. 4) Global sclerosis, tubular atrophy and interstitial fibrosis were noted in 39.8, 16.1 and 11.3% of primaty MN, respectively. IgG and C3 were deposited on the glomerular capillary loop in 92.7% and 29% of primary MN patients. There was no significant correlation between the electron microscopic pathologic stage and clinical findings. 5) Of 56 patients with primary MN followed more than 6 months, 50(90.9%) patients were treated with prednisolone, cyclophosphamide or cyclosporin. Complete remission was obtained in 29 patients(51.8%), partial remission in 6 patients(10.7%), and no response in 18 patients(32.1%). Of 6 patients who were not treated with immunosuppressive drugs, 3 patients showed spontaneous complete or partial remission. Three patients who did not show clinical improvement progressed to end-stage renal failure. There were no significant clinical difference including renal pathology at the time of diagnosis between the patients who showed complete or partial remission and patients who did not. In conclusion, it was difficult to predict the long-term prognosis of primary MN at the time of diagnosis, clinically. The response to therapeutic modality would be the most important to predict long-term prognosis of primary MN.
