Studies on diagnosis and treatment of tumor . abscess . ulcer in intestinal carbuncle were carried out. The result of studies were summerized as follows: 1. By Nai-Gyung carbuncle-tumor arose from disharmony between nutrient and defensive because of cold, abscess arose from fever victory between cold and fever, ulcer arose from decreasing function of Bi-Kam year. By latter literature Bi-Kam year could be interpreted that spleen stomach was invaded evil influence from unattainable vital force of the earth. 2. Sites of intestinal carbuncle were large intestine, small intestine, intestinal inside or outside between large and small intestine, Intestinal carbuncle was common name of a disease about large intestinal carbuncle, small intestinal carbuncle, pelvic intestinal carbuncle, shrink leg intestinal carbuncle etc.. Pain appeared Chunchu-Hyul in large intestinal carbuncle, and Gwanweon-Hyul in small intestinal carbuncle. 3. On abdominal diagnosis tumor had indistinct pain of Gwanweon Chunchu, edema and heary feeling in low abdomen, no excessive pain by hand press and intestinal boiling sound. In abscess pain descended from right side of low abdomen to huckle, and there was rejection against press, feeling about fever,water sound with flank movement. In ulcer hand approach was difficult since excessive pain diffuse to whole abdomen, and perforating ulcer sometimes caused a serious symptom of umbilical pus. 4. On fecal and urinary diagnosis in tumor urine was yellowish red pollakiuria like gonorrhoea and occasional constipation. In abscess uncomfortable rough pain short red early urine like gonorrhoea appeared during urination, and constipation with stinging pain appeared during defecation. In ulcer red rough pyuria appeared, and stinging and pain with puruloid blood appeared during defecation. 5. On treatment in tumor Daiwhang-Tang Daisenggi-Tang Dangui-Jun by dissipation method, calming down method, interior reliance maturation method, in abscess Mokdan-San Euiiin-Tang Jeokduiin-Tang by the method of water repelling pus discharge, acute breaking, in ulcer Takridanggui-Tang Paljin-Tang Bojungikki-Tang were each used by the method of interior reliance, virulence astriction, supplement vital force and blood, supplement spleen stomach. 6. On treatment patient may have to be careful of excessive moving and suprising anxiety. Abuse of acupuncture and moxibustion made patient worse, misuse of analgesics purgative intestinal irrigation etc. could provoke difficult diagnosis and perforation. So you must treat after exact diagnosis. 7. Prognosis of ease tumor ease abscess ease ulcer and ease astriction was good. If the intestinal carbuncle were not to promote to abscess and ulcer for a long time, its prognosis was bad and it could metastasize to cancer because of dark purple with hardness. So tumor abscess ulcer in intestinal carbuncle may be significant of precancerous lesion.

스마트폰 기술의 발전으로 인하여 2020년 기준 전 국민의 91.9%가 인터넷 이용[1]하여 수시로 홈페이지와 모바일 앱을 통해 정보를 습득하고 있다. 정보제공을 담당하는 홈페이지의 수가 점점 늘어남에 따라 홈페이지의 안전성을 진단하는 웹취약점 진단 신청수도 매년마다 증가하고 있는 상황이다. 기존 웹취약점 점검은 진단원이 수작업으로 홈페이지를 모의 해킹하여 취약점을 진단했기 때문에 진단대상 홈페이지 수에 비례하여 진단인력이 늘어나야한다. 하지만 현실적으로 웹취약점 진단인력 확보에 한계가 있고, 진단인력을 늘렸을 경우 많은 비용이 발생한다. 이러한 문제점 해결을 위해 자동진단 도구를 사용하여 수동진단의 일부를 대체하고 있다. 본 논문에서는 현재의 자동진단 범위를 확대하기 위한 방안을 새롭게 제안하였다. 즉, 웹취약점 진단항목의 영향도를 분석하여 자동진단 가능 항목을 도출하고, 실제 운영 중인 홈페이지에 수동 및 자동진단을 수행하여 진단결과에 대한 비교 분석을 통해 자동진단 가능항목을 파악하였다. 또한 자동진단 개선방안을 제시하여 자동진단 도구 개선을 통해 모든 취약점 항목은 아니지만 가능한 항목에 대해서 수동진단을 대체할 수 있다. 이를 통해서 진단 및 정밀진단이 필요한 부분에 집중하여 안전한 홈페이지 운영환경 조성에 기여할 수 있을 것이다.

The rapid and correct isolation of faulty submodules (SMs) is of great importance for improving the reliability of modular multilevel converters (MMCs). Therefore, a fast diagnosis method containing fault detection and fault location determination was presented in this paper. An improved incremental predictive model of arm current was proposed to detect failures, and the multi-step prediction method was used to eliminate the negative impact of disturbances. Moreover, a control method was proposed to strengthen the fault characteristics to rapidly locate faulty arms and faulty SMs by detecting the variation rate of the SM capacitor voltage. The proposed method can rapidly and easily locate faulty SMs under different load conditions without the need for additional sensors. The experimental results have validated the effectiveness of the proposed method by using a single-phase MMC with four SMs per arm.

The result of examination of diagnostic method, which is composed of a combination of a thermal camera and a drone that visually shows the temperature of the object by detecting the infrared rays, for detecting the leakage of earth dam was driven in this research. The drone infrared thermography method was suggested to precise safety diagnosis through direct comparing the two method results of electrical resistivity survey and thermal image survey. The important advantage of the thermal leakage detection method was the simplicity of the application, the quickness of the results, and the effectiveness of the work in combination with the existing diagnosis method.

This paper describes a new method of pseudorandom testing of a digital circuit by use of correlation method and a neural network. The authors have recently proposed a new method of fault diagnosis of logical circuit by applying a pseudorandom M-sequence to the circuit under test, calculating the crosscorrelation function between the input and the output, and comparing the crosscorrelation functions with the references. This method, called MSEC method, is further extended by using a neural network in order to not only detect the existence of faults but also find the place or location of the faults. An experiment by using a simple digital circuit shows enough applicability of this method to industrial testing of circuit board.

Objectives : The purpose of this study is to investigate the concept of the Chukbu(尺膚) diagnosis in Huangdineijing(黃帝內經) and explain the characteristic of Chukbu(尺膚) diagnosis and causes of its clinical applicational decline. It will help the application of the Chukbu(尺膚) diagnosis to clinical treatment. Methods : The Sikuquanshu(四庫全書) database and Traditional Chinese Medical(TCM) books web database were used. The related contents of the Chukbu(尺膚) diagnosis in Huangdineijing (黃帝內經) and its annotation books were analyzed. The mentions on the Chukbu(尺膚) diagnosis in other medical books were examined. Results & Conclusions : The Chukbu(尺膚) diagnosis is important in the diagnostic system of the Huangdineijing(黃帝內經). The Chukbu(尺膚) diagnosis is composed of inspection and palpation. Its characteristic is something different compared to that of the Chongumaek(寸口脈) diagnosis; it relatively diagnoses condition of exterior disease(表病). The causes of its clinical applicational decline are relative inconvenience, limits of feudal society, and development of Zangfubianzheng(臟腑辨證) in that era.

인체 생리의 부조화에 의한 기능적 이상 진단이 가시화 장비나 임상병리 소견으로도 진단할 수 없는 경우가 있기 때문에, 현대과학과 의공학의 특성을 접목한 EFG(Electro Functio Gram：기능전도) 측정 개념의 진단기술 개발이 요구되고 있다. 따라서 이러한 기능적 진단기술을 이용하여 양ㆍ한방 모든 분야에서 기초 진단기로 사용할 수 있는 재현성과 신뢰성, 편리성을 갖춘 범용의 진단시스템으로 개발하였다. 또한, 한의학적진단 및 치료를 위한 기와 혈의 인체 순환을 진단할 수 있는 사지 8CH(양,음경락), 두부 2CH 동시계측 방법 및 일괄 부착식 전극을 개발하였다. 성인 남자 20명(정상인)을 대상으로 한 임상데이터 분석결과, 인체의 12경락의 상태 및 자율신경계통의 상태를 진단할 수 있어서, 진단장비로써의 유의성을 확인하였다. 따라서, 본 논문에서는 인체 12부위의 음경락 양경락을 측정할 수 있는 H/W 및 S/W을 구현하고, EFG 체계를 구축하여 생체-전기적 반응에 의한 한의학적 진단 시스템을 설계하였다.
