      • 비선형시스템을 위한 PID형 퍼지-신경회로망 제어방식

        임중규,이정훈,엄기환 동국대학교 대학원 1998 大學院硏究論集-東國大學校 大學院 Vol.28 No.-

        In this paper, a novel scheme, directly using the PID-type fuzzy-neural network logic system as a controller, is proposed for the control of a class of nonlinear dynamical systems. The advantage of the proposed control method is simple to design a controller for unknown nonlinear systems because of learning ability. In order to verify excellent control performances of the proposed control method, we compared with a general fuzzy-neural network control method with one link manipulator. The proposed control method has the very superior tracking characteristics.

      • EMG 신호의 패턴 분류를 위한 간단한 SOM 방식

        임중규,엄기환,Lim, Joong-Kyu,Eom, Ki-Hwan 대한전자공학회 2001 電子工學會論文誌-SC (System and control) Vol.38 No.4

        본 논문에서는 근육의 움직임에 의해 유발되는 전기적 선호인 근전도(EMG) 신호를 신경회로망을 통해 분류하여 인체의 움직임을 파악하는 방법을 제안한다. 신호분류를 위한 신경회로망으로 학습에 의해 스스로 출력뉴런을 구성하는 SOM을 사용하였으며, 기존의 방식과 다르게 전처리 과정 없이 신호자세를 SOM의 입력으로 사용하여 패턴을 분류하는 간단한 방식이다. 실험과 시뮬레이션을 통해 제안한 방식의 유용성을 확인하였다. In this paper we propose a method of pattern classification of the hand movement using EMG signals through Self-organizing feature map. Self-organizing feature map is an artificial neural network which organizes its output neuron through learning and therefore it can classify input patterns. The raw EMG signals become direct input to the Self-organizing feature map. The simulation and experiment results showed the effectiveness of the classification of EMG signal using the Self-organizing feature map.

        本 論文에서는 Segre imbedding의 성질을 증명하고, 특히 의 여러 성 질을 생각해 보았으며, 이것이 P2와는 isomorphic 하지만 birationally isomorphic 하지는 않는다는 것을 대수적으로 보였다.

      • 동적 신경회로망을 이용한 미지의 비선형 시스템 제어 방식

        정경권,임중규,엄기환 한국정보통신학회 2002 한국정보통신학회논문지 Vol.6 No.3

        본 논문에서는 동적신경회로망을 이용한 미지의 비선형 시스템 제어 방식을 제안하였다. 제안한 방식은 비선형 시스템의 상태 공간 모델과 유사한 형태의 신경회로망을 구성하여 비선형 시스템을 식별하고, 식별한 정보를 이용하여 제어기를 설계하는 방식이다. 제안한 방식의 유용성을 확인하기 위하여 단일 관절 매니플레이터를 대상으로 시뮬레이션을 수행한 결과 우수한 제어 성능을 확인하였다. In this paper, we proposed a control method of an unknown nonlinear system using a dynamical neural network. The proposed method is composed of neural network of state space model type, performs for a unknown nonlinear system, identification with using the dynamical neural network, and then a nonlinear adaptive controller is designed with these identified informations. In order to verify the effectiveness of the proposed method, we simulated one-link manipulator. The simulation results showed the effectiveness of using the dynamical neural network in the adaptive control of one-link manipulator.

      • 中等敎師를 위한 數學敎育에 관한 硏究

        宋炳檜,任中圭 全南大學校 師範大學 科學敎育硏究所 1977 科學敎育硏究誌 Vol.2 No.1

        It is often said that the characteristics of a mathematics teacher must be enhanced as a professional man like a medical man or a pharmacist by intensifying his qualifications. At present, the training course is of a diverse nature according to the different colleges(e.g. college of education, college of liberal arts and sciences), and even according to the national or private college of education. Hence, there is no fixed standard for qualification control for a mathematics teacher. In this article, a tentative plan is made by analyzing and adapting the mathematics curriculum of Japan's for the purpose of producing a better mathematics teacher, claiming good quality plus a good knowledge of a teacher,

        갑상선 결절에서 T1-201 주사의 진단적 의의

        김순호,임중규,정경헌,김기현,박철성,문정식,이재학,허진득,조형석,손장신 대한내분비학회 1996 Endocrinology and metabolism Vol.11 No.2

        To investigate diagnostic value of Thallium 201(T1-201) thymid scan in differentiating malignant nodule from benign, 135 patients with thyroid nodule were evaluated with Tl-201 thyroid scan, fine needle aspiration(FNA), clinical characteristics and laboratory data. Each had histological diagnosis after thyroidectomy. Tl-201 scan had a sensitivity of 67.3% and a specificity of 66.3% and FNA had sermitivity of 46.9% and specificity of 100% in predicting malignancy. As the size of thyroid nodule and age of patient incteases, diagnostic value of 11-201 thyroid scan was improved. In the thyroid nodules larger then 3cm, sensitivity, specificity and negative predictive value were 100%, 70% and 100%, reqectively. By cornbining Tl-201 throid scan and FNA, sensitivity had 91.8%. From the data we conclude that Tl-201 thyroid scan is valuable with adjuvant diagnostic method in differentiating malignant fmm benign thyroid nodule and treatment planning(J Kor Soc Endocrinol 11:175~181, 1996).

        Albumin Enriched Peritoneal Dialysis 를 시행한 급성 황산동 중독 1 예

        박홍배,임중규,이상운 대한내과학회 1987 대한내과학회지 Vol.33 No.6

        A twent-three-year old male was admitted because of jaundice and hematuria. Two days before entry, he ingested copper sulfate (about 30 gm} for suicidal purpose. The third admission dacy, sudden decreased urine output was developed and mental deterioration was followed inspite of using chelating agents (D-Penicillamine 500mg, q 6 hours). So, peritoneal dialysis with added albumin (20% albumin + Inperinol, 10 times) was performed. The amounts of copper removed by peritoneal dialysis with albumin was significantly greater than that removed by dialysis without albumin (36 ug/dl: 2.1 ug/dl). Daily urine output, renal function test and other laboratory findings were improved after dialysis. The patient discharged on 13th admission day without any complications. Chelating agents form a copper complex, which is readily excrete in the urine, but the renal failure precludes the effectiveness of these drugs. So we conclude that albumin enriched peritoneal dialysis is effective method for management of the renal failure in acute copper poisoning.

        말단거대증을 동반한 Albright 증후군 1 예

        임동명,김순호,임중규,허진득,장진형,김훤,위대철,윤철승 대한내분비학회 1992 Endocrinology and metabolism Vol.7 No.4

        The syndrome of polyostotic fibrous dysplasia (PFD), cutaneous pigmentation and endocrinopathy (Albright's syndrome) continuous today to remain enigmatic. Not all patient with PFD have complete syndrome. In addition to the described in Albright's original patients, other endocrinopathies have been reported, including hyperthyroidism, acromegaly, hyperparathyroidism, Cushing's syndrome, adenoma of pituitary, thyroid, parathyroid and adrenal gland, vitamine Dresistant rickets and hypothalamic hypogonadotrophic hypogonadism. A 27-year-old man was found to have polyostotic fibrous dysplasia of bone, cutaneous pigmentation and acromegaly with diabetes mellitus. He started to have pain in left hip joint and it caused an alternation on his gait in 1983. X-ray study revealed that he had fibrous dysplasia. He gradually developed clinical feature of acromegaly. Subsequent biochemical study of growth hormone and radiologic study of the sellar confirmed the diagnosis of acromegaly. Bone biopsy and microscopic examination of the pituitary tumor tissue obtained through transsphenoidal procedure were reported to be fibrous dysplasia and acidophilic adenoma, respectively. The purpose of this report is to describe a patient with incomplete Albright's syndrome with acromegaly, which is very rare and we believe this is the first case to be reported in Korean literature.(J Kor Soc Endocrinol 7:402~408, 1992)
