        《 難經 》의 臟腑虛實에 따른 鍼灸補瀉法에 關한 硏究 : 體質針 原理에 關한 硏究(Ⅰ)

        윤종화,김주경,손성철 대한침구학회 2001 대한침구의학회지 Vol.18 No.6

        Obejective : Based on 《sixty-ninth Nan》 (《難經·六十九難》) the interpromoting of the five element's balance method to discuss following "when deficiency than should strengthen mother and when excessive than eliminate son" theories. Method : This strengthening and eliminating method is based on Jang-bu organ's balance method when "east is excessive (liver excessive (肝實 )) and west is deficiency (lung deficiency (肺虛))" then "eliminate the south and strengthen the north "'s method. Results : The seventy-fifth Nan (《難經·七十五難》) explains" son effects mother's excessive and mother effects son's deficiency " theory where it balance method of the inter-overacting five elements controlling Jang-bu organ's differentiations. The eighty-first Nan (《難經·八十一難》) explains strengthening-eliminating method of "lung excessive and liver deficiency." Since there are two different perspective of seventy-fifth and eighty-first Nan, we must compare and discuss to make right point of view. Conclusion : the treatment method in 《Nan kyoung sixty ninth nan》 could be understood as a view of five element constitutional theory (五行體質理論), the treatment method in 《Nan kyoung seventyty-fifth nan》 of eleminating fire and strengthning water in case of liver excess and lung defficiency and the treatment method in 《Nan kyoung eighty-first nan》 of strengthning liver and eleminating lung in case of lung excess and liver defficiency could be understood as a view of the yin-yan constitutional theory (陰陽體質理論).

        논문 : 한국 근현대 낙동강 유역의 수리조합 연구 -경상북도 칠곡군의 수리조합을 중심으로-

        손경희 ( Kyoung Hee Son ) 대구사학회 2013 대구사학 Vol.111 No.-

        A Study on the Irrigation Associations in the Nakdong River Basin of Modern and Contemporary Korea - Focusing on the Irrigation Associations of Chilgok County, North Kyeongsang Province - Son, Kyoung-hee [Abstract] Founded in Gyeongsangbuk-do, Chilgok this time, the Irrigation Association, both established before the fierce opposition movement that happened was common. Indong Irrigation Association has driven the establishment in 1927. At the time, it hasn`t been established by protest of people of a township until 1931. When Indong Irrigation Association was established, the rate of opposition reached up to 27%, the movement of antagonism wasn`t occurred. Yakmok Irrigation Association was established in 1934. In 1924 the Irrigation Association tried to apply for the 38m irrigated area establishment but it ran into strong opposition. The counter action was not temporarily occurred and it was kept for a long time. In early 1925, a petition which requests the annulment for the unfair Association establishment through people of a township`s joint of signature. The people have objected actively and the injustice of the business came out so that the Government General finally has pulled back the Irrigation Association approval. After that, Yakmok Irrigation Association applied for the 155m irrigated area establishment once again in 1926. But Yakmok Irrigation Association wasn`t established at the time. Yakmok Irrigation Association has been pushed ahead fully 11 years later. After the establishment, the counter action was still on. Sukjeok Irrigation Association was established in 1944. But, on 12 February 1938, a Irrigation Association establishment movement has been occurred in this area. Sukjeok Irrigation Association member was total 361 including 196 assentient and 165 dissenters which has only 54% of assentient. Buksam Irrigation Association has been established in 1944, it has already been worked with the establishment in 1931 however, it was cancelled by a counter activity. The purpose of this association was irrigation improvement and the irrigated area was 290m. Wheguan Irrigation Association was established on 25 March 1952. As Land Improvement project law 948, it has been renamed and combined as Land Improvement Association on 30 December 1961. Indong, Sukjeok and Wheguan Irrigation Association was combined as Chilgok Land Improvement Association, Yakmok and Buksam Irrigation Association was combined as Yakmok Land Improvement Association. The purpose of Wheguan Irrigation Association Establishment was Improved irrigation. Wheguan Irrigation Association was about 207m and as an irrigated area, it was 200m. Wheguan Irrigation Association has 75% subsidy, 18% of region burden charge, 6% of loan flotation so that the establishment of Irrigation Asscociation was mostly relied on the government. Repair policy which was in progress under Japanes imperialism was not changed much and continually happened.

      • 하드웨어 논리 시뮬레이션을 위한 VHDL표현으로부터 회로 정보 추출

        손소라,민경숙,전중남 충북대학교컴퓨터과학연구소 1995 컴퓨터과학연구 Vol.3 No.1

        VLSI 기술의 급속한 발전과 더불어 칩의 복잡도가 증가함에 따라 칩 설계를 지원하는 설계 자동화 도구의 필요성이 증가되고 있는 현실이다. 실제로 하드웨어 합성기, 하드웨어 시뮬레이터등과 같은 많은 설계 자동화 도구들이 이용되고 있다. 하드웨어 논리 시뮬레이터는 자동 설계된 회로의 정확성을 검증하기 위한 설계 자동화 도구이다. 시뮬레이터에 있어서 테스트하고자 하는 시스템의 동작 특성과 상호 간의 연결 관계 및 설계의 문서화를 효율적으로 표현하는 것은 매우 중요하다. 그런 면에서 VHDL(VHSIC Hardware Description Language)은 표준화된 하드웨어 기술언어(Hardware Description Language)로써 하드웨어의 사양을 표현하는 통일된 규격을 제공한다. 본 논문에서는 하드웨어 논리 시뮬레이터가 다른 설계 자동화 도구와의 호환성을 유지하면서 시뮬레이션을 효율적으로 수행할 수 있도록 VHDL로 기술된 회로 표현을 전처리하는 VHDL분석기에 대하여 연구하였다. VHDL 분석기는 VHDL로 기술된 회로 표현과 입력 신호를 VHDL의 문법에 따라 분석하고, 시뮬레이션을 위해 요구되는 정보인 회로 연결 정보와 회로를 구성하고 있는 소자들에 대한 정보 그리고 입력 신호 정보 등을 추출하여 중간 코드를 생성하고, 이를 라이브러리로 구성함으로써 시뮬레이션 시스템이 계층적으로 내부 표현을 모델링하는 기능을 제공한다.

        아세톤 함유 상아질 접착제의 습윤 상아질에 대한 전단 결합강도

        손호현,김경남,이광원 大韓齒科器材學會 1994 대한치과재료학회지 Vol.21 No.2

        The purpose of this study was to investigate whether or not the wetting of dentin compared to the dried dentin influences the shear bond strength of strong, hydrophilic dentin bonding systems particularly containing acetone. Three dentin bonding systems (i.e. All Bond 2, Mirage ABC, Tenure S) with primers possessing strongly hydrophilic properties were applied to air-dried and moist dentin individually. After the shear bond strength of three dentin bonding systems were evaluated, and then the sheared specimens were examined by light optical and scanning electron microscopy(Hitachi, Japan) to determine the location and appearance of the fracture. The following results were obtained. 1. The enhancement of shear bond strength to moist dentin compared to air dried dentin existed within groups treated with All Bond 2. (p<0.001) 2. A statistically significant difference of shear bond strength did not exist between moist dentin and air-dried dentin within groups treated with Mirage ABC and Tenure S.(p>0.05) 3. The deep cohesive fracture of dentin was appeared within all the moistened specimens treated with All Bond 2. On the contrary, the air-dried specimen S did not show any cohesive fracture of dentin except one. 4. All the moist and dry specimens treated with Mirage ABC and Tenure S did not show any cohesive fracture of dentin.

        The purpose of this study was to analyze the professionalism of elementary school teachers and to draw out factors which elementary teachers should try to improve their professionalism for environmental education. For the study, both Quantitative analysis and qualitative methodologies were applied: First, randomly selected 483 elementary teachers from Seoul and Gyeonggi self responded to 5 evaluation areas by Hungerford et al. (1994) to evaluate their environmental education professionalism through the use of five point Likert scale. Second, 2 elementary teachers' environmental classes were observed for the purpose of analyzing strengths and weaknesses in classroom instruction, and then the results of self-evaluation on environmental education professionalism and teacher professionalism as shown in the classes were compared. It was found that 483 elementary teachers including 2 teachers for analyzing classroom instruction who performed a self-evaluation gave themselves mid-scores on the Hungerford et al.'s 5 evaluation areas. However, the result of self-evaluation did not correspond with the result of actual class observation and teacher interview. That is, the actual environmental classes conducted by 2 teachers did not seemed to reflect the evaluation areas which were the foundation of the study: the conceptual awareness, the investigation & evaluation, environmental action skills, and educational application. The results of this study can be used as the basis reference to develop teaching-learning program and in-service programs for professional development of teachers for successful application of environmental education in elementary school classes.

      • S.I. 기관 밸브시스템에서의 이상연소에 관한 실험적 연구

        박경석,한성철,장석형,손성만 경희대학교 산학협력기술연구원 2002 산학협력기술연구논문집 Vol.8 No.-

        The suction pressure of an abnormal condition spark ignition engine which has non adjusting intake valves becomes reduced and residual gas increases at a greater rate than under normal combustions. This reduction in suction pressure is caused by the distribution of in equalable air in a cylinder leading to abnormal combustion. If this condition continues, the engine ceases due to an increase in engine heat loss. In this study, we conducted tests to determine the combustion characteristics of a spark ignition engine under both norman and abnormal conditions. The results of this study will establish basic data analysis for developing an automotive diagnosis system by analyzing some of the factors including pressure in the cylinder, output signal of the MAP Sensor and Exhaust gases.

        박양호,손효진,김경주,권규혁,이중헌 한국공업화학회 2003 응용화학 Vol.7 No.1

        In this study, the hybitd reactor has used to remove H_2S from the toxic gas. Since the oxidation and reduction reactors were combined, theri sizes were important to stabilize developed process. The optimal sizes of oxidation and reduction reactors were determined considering iron oxidation rate and H_2S removal rate. The optimal ratio of reactor size was 4 L for oxidation reactor to 1 L for reduction reactor.Immobilized Thiobacillus ferrooxidans has been developed to minimize the size of oxidation reactor. Since the immobilized cell enhanced the oxidation rate, it was possible to incrase H_2S removal efficiency. It was possible to incerase operation time because immobilized cell can survie lger than free cell.
