Through the classical records of the oriental medicine my investigation of the authorities of the epilepsy by classifying the etiology, symptoms and the treatments of it and camparing them has led to the following conclusion. 1) The etiology of 'epilepsy' can be classified into wind(風), sputum(痰), fever(熱) convulsion and caul. 2) The symptoms of it fall into the following nine ones; Sudden strong contraction making Sounds within the mouth, unoonsciousness, mutual jerks of the facial muscules foaming form the mouth, trismus contractive of extremities general body rigidity recovering after the fit and no rest. 3) The symptoms of Epilepsy are classified into 'Um type epilepsy'(癲) and the 'yang type epilepsy'(癎), and then the former has nine kinds in sympatomatic state and latter seventeen. 4) The treatment of the case can be made by using of cold drugs mainly for the purpose of mind purification(淸心), fever abatement(降火), Sputum-elimination(化痰) and normalization of metabolism(順氣) and Sometimes the function of the liver should be normalized by giving liver function normalizing medicine after Emetics. In comparison with the western way of using Anti convelsents therapy and electricshock therapy, the way of its treatment based on the classification of the causes is considered to be far more desirable.

산업분야에서 품질불량이 반복적으로 발생하는 이유는 근본 원인을 찾지 못한 채 표면적이고 한시적인 조치를 취해 왔거나, 발생 고장과 시정조치 내용을 적절하게 관리 및 전파하지 못한 데 있다. 본 논문에서는 방위산업에서 고장 발생 시 근본 원인 분석과 적절한 시정조치가 이루어진 후, 그 정보를 어떻게 저장하고 활용할 것인지에 대해 다룬다. 운용 단계뿐만 아니라 개발 및 양산 단계에서도 적극 활용할 수 있는 지식기반의 통합 고장정보 관리체계 도입의 필요성을 설명한 후, 고장 및 개선 정보를 효과적으로 저장하고 공유할 수 있도록 고장지식관리 아키텍처를 제안하고, 방위산업 특성에 맞는 활용방안과 사용자 편의를 도모할 수 있는 몇 가지 추가 장치를 소개한다.

궤도차량 변속기용 축압기 국산화 개발

이일랑,김성일 한국기계기술학회 2020 한국기계기술학회지 Vol.22 No.2

Unlike wheeled vehicles, tracked armored vehicles require a highly developed transmission technology since the transmission has to not only shift gears but also steer and brake the heavy ground weapon system precisely. Even though weapons systems including the K00 Infantry Fighting Vehicle (IFV) have recently been developed with domestic technology, it is true that many core parts in the systems are still being imported. In this paper localization process of the accumulator which is one of the most important hydraulic parts in the K00 transmission is introduced. In order to determine design variables such as operating pressure we analyzed torque characteristics of the transmission and calculated spring constant by disassembling the original accumulator. And tests such as durability, safety, etc. were conducted to assure the validation of the development. We expect that the process of reverse engineering we adopted will be helpful to localize similar hydraulic parts.

궤도차량 엔진용 공기정화기 검증에 관한 연구

이일랑,김상부 한국산업융합학회 2020 한국산업융합학회 논문집 Vol.23 No.3

The air cleaning unit of K00 IFV(or Infantry Fighting Vehicle) has important roles to make sure the engine of the vehicle works precisely as filtering foreign substances in the air such as dust and sands. The entire components including scavenge fan which is one of the important inner part of the air cleaning unit are developed so that we can produce it domestically and don’t need to import it from P** Co., the original maker in United Kingdom. This paper introduces a few verification processes including cleaning efficiency and reliability. As this core unit has developed successfully the improvement of military strength and logistics support can be expected. And design capability, manufacturing skills, maintenance ability of tracked weapon system will be increased thanks to the accumulated technical knowledge obtained from this developing project. Foreign currency savings and reducing operational cost can be expected as well in military industry.

In Oriental Medicine Hyangso - san was applied widely to the neurosis and the neurasthenia caused by the disharmony of Vital energy. Hyangso-san was composited of five herb drugs : Cyperi Rhizoma, Perillae Folium, Atractylis Rhizoma, Aurantii nobilis pericarpium and Glycyrrhizae Radix. This study was undertaken in an attempt to investigate the effects of Hyangso - san and Cyperi Rhizoma on the motility of isolated intestine in rabbits and atria in rats. The following results were obtained : 1. Motilities of isolated intestine in rabbits were released in proportion to the concentration of Hyangso-san(8×10^(-4)g/㎖)and Cyperi Rhizoma (4×10^(-4)g/㎖). 2. Samples were antagonized significanty against contraction of the rabbit-intestine by the acetylcholine chloride. 3. Samples did not contracted the relaxed intestine by the pretreated drugs, but samples were slowly shown the relaxation to the contracted intestine by the Bacl₂. 4. Motililes of isolated atria in rats were released to the concentraction of Hyangso-san ( 2×10^(-3)g/㎖) and Cyperi Rhizoma ( 1.5 × 10^(-4)g/㎖). 5. Samples were shown the relaxation to the contracted atria by pretreated epinephrine, and Hyang so - san reacted remarkably but Cyperi Rizoma did slowly.

Throush tho classical recoeds of the oriontal modicino my. lnvostigation of the epilepsw by classifying tho otiology, symptoms and tho following concjusion. 1. The otiology of "epilopsy" can be classified into wind(風), sputum,(痰) fever(熱) convulaion and caul. 2. The symptoas of it fall into the follouing nino ones; Suddon strong contraction making sounds within the mouth, unoonsciousnoss, mutual jerks of the facial musoules foaming from the mouth, trismus contractive of extremitics general body rigidity recovering immediately after the fit and no rest. 3. The symptoms of Epilepsy are classified into "Um type epilopsy" (癲) and the "Yang type epilepsy" (癎), and then the former has nine kinds in sympatomatic state and the latter seventeen. 4. The traeantment of tfe case can be made by using or cold drugs mainly for the purpose of mind purafication (淸心) fever abatement(降火) putum-climination(化痰) and normaligation of metabolism(淸心) and sometimes the function of the liver should be nor normalijed by giving liver funotion normnlizing after Enetion. In comparison with the western way of using Anti convelsents therapy und electricshock therapy, the way of its treatment based on the classification of the cauoes is confidered to be far moro dosirable.

로봇경로 생성을 위한 방해물 옵셋 알고리즘

In this paper, an method to offset obstacles consist of triangular mesh is presented; this method focuses on the elimination of theoretical offset errors and the prevention interferences at the concave region. In the conventional method, the first step is the vertex splitting process; after performing a small offsetting process such that the disappearance of the edges of the mesh is not affected, the vertex with more than n = 4 incident faces is separated into (n?2) vertices consisting of exactly three incident faces. The obtained initial offset mesh has certain valuable properties. In the second step. the mesh structure is updated by the offset process of the vertex split mesh, which was obtained from the first step, with respect to the offset distance. This paper focuses on this first step dealing with vertex split mesh.
