        齒髓病變에 따르는 局所血液像에 關한 硏究

        李鳴鍾 大韓齒科保存學會 1980 Restorative Dentistry & Endodontics Vol.6 No.1

        ABSTRACTThe purpose of this study was to determine the close relation between clinical symptom and histopathologic finding in pulp. 20 samples of pulp tissue were collected from badly decayed teeth with considerable pulp vitality. Hemogram was also made with the first drop of bleedieg after total pulp extirpation (lOcases) and vital pulpotomy(lOcases). Histologic specimen was made routinely with extirpated pulp and stained by H&E and P.A.S. Stains.The results under microsopic examination were as follows; 1. Hemogram obtained from dental pulp with acute inflammation revealed increase of polymorphonuclear leukocyte in number, more lymphocytes and monocytes. 2. Hemogram from pulp with chronic inflammation shown the number of lymphocyte and monocyte was remarkably increased. 3. Histologi specimen obtained from teeth with severe clinical symptome showed polym- orphonuclear leukocyte infiltration and the hemogram also showed polymorphonuclear leukocytes. 4. Specimen from teeth with moderate symptom showed lymphocyte infiltration and vessel dilatation underneath decayed area. Erythrocytes were massively accumulated inside of the vessel wall.

      • 공기업 품질경영혁신 성과 연구 : 한국 전력공사의 품질경영을 중심으로

        이명종,김종순 江原大學校 經營硏究所 2002 經營科學硏究 Vol.28 No.-

        국경 없는 경쟁에서 기업의 생존을 위한 많은 경영도구들이 제시되어 오고 있다. 최근년에는 품질경영, 지식경영, 곡객감동경영, 경제적 부가가치(EVA) 경영등등의 경영기법들을 각 기업에서 적용하고 있다. 이런 경영기법들은 각각 기업의 외부환경과 내부역량을 강점(强點)과 기회(機會)로 세계의 경재력을 제고하기 위한 도구들이다. 품질경영은 우리나라의 품질보증시스템 규격(ISO 9000)과 더불어 도입된 경영도구의 하나이다. 공기업인 한국전력도 경영 혁신의 일환으로 품질경영을 도입하여 품질전문가의 지도ㆍ자문, 사ㆍ내외 품질교육, 품질개선 활동, 그리고 사내품질경영상 수상실적으로 품질경영풍토를 정착시키고자 노력해 왔다. 특히 1997~1999년에 걸쳐 품질경영 지도ㆍ자문의 용역을 시행하여 공사 품질경영 모형 정착 및 확산연구도 이미 이루어져 왔기 때문에 여러 분야에서 품질관리, 품질개선 활동을 활성화하는 등 그 성과 측정이 기대되었다. 본 연구 목적은 한국전력의 품질경영성과를 분석하는 것을 중심으로 하여 공기업의 품질경영 개선 방안을 제시하는데 있다.

        삼림토양의 질소의 존재형태에 관한 연구

        이명종 한국임학회 1993 한국산림과학회지 Vol.82 No.3

        The composition of the nitrogen forms of the organic layer and mineral soil horizons of 8 differing soil type was measured to find a clue to elucidate the problem on the fertility- and nitrogen availabilities of forest soils. The ratio of inorganic N(NH₄-N+NO₃-N) to total N was very low in every 0 layer and its maximum was only about 2%. And the inorganic N concentration of every mineral soil horizon was low, and the maximum of its rate to N was 3.7% in surface horizon and about 4.1% in lower horizon. Organic N form of O layer were characterized by the decrease of aminoacid-N, and the increased of hexosamine-N and amide-N according to the advance of decomposing process. The ranges of hydroly-zable-N of every flesh litter, F and H layer of the selected soils were about 80-90% and they- were hardly affected by the differences of tree species and decomposing process. The organic N form of every litter was similar and it was follows : aminoacid-N was not abundant and it ranges were about 40-50%, more than half of hydrolyzable-N. The hexosamine-N was eery poor and it ranged to only 2-7%. The amide-N teas low and about 10-23%. No distinguished difference was seen between the organic N forms of the O layer and surface horizon of dry and wet soils in brown forest soils.

        1910년대 조선 농민의 만주 이주와 ≪매일신보≫ 등에서의 ‘만주식민지’론

        이명종 한국근현대사학회 2016 한국 근현대사 연구 Vol.78 No.-

        In 1910s, a large number of the Korean peasants had been emigrated to Manchuria. They had complaints on the political and economic pressure from the Japanese colonial rule. The majority of these peoples had been not only languished in poor in Korea but also had gone to live as poor peasants and workers in Manchuria. Particularly they considered the Gando as a utopia, and then they emigrated to that province. Some peoples whose had a anti-Japanese consciousness thought the Gando as a land of freedom. As a mouthpiece of the Japanese Government-General of Korea, THE MAIL-IL SHINPO regarded the emigratory Koreans as losers in struggle for existence, and described the Gando as a hell, and actively opposed Korean emigration to Manchuria. Since Japan and China formed an ‘Agreement of Nam-Man-Dong-Mong’ in May 1915, however, THE MAIL-IL SHINPO highly had been encouraging Koreans to emigrate to Manchuria. After those times THE MAIL-IL SHINPO compared emigration to Manchuria to the recovery of Korean lost territory. And then claimed that Manchuria and Korea had been maintaining a indivisible relationship as the same one. This claims came from the perspective of the continents invasion to make Manchuria into the territory of Japan. The intellectual who have been cooperating in this policy of THE MAIL-IL SHINPO was Ji-yeon Jang. THE MAIL-IL SHINPO and Jang had regarded Manchuria as the Korean colony. This discourse conceiving of Manchuria as the Korean colony had played a role of interfering with the Korean independence movement in Manchuria. These discourses had distorted the desire of the Korean peoples for opposing to economic deprivation and the Japanese rule. 1910년대에는 많은 조선 농민이 일제 치하의 정치경제적 압박에 대한 불만을 품고 조선을 떠나 만주로 이주했다. 만주에 거주하는 조선인이 1909년에 약 21만 명이었는데 1919년에 이르면 43만여 명이나 되었다. 이들의 대다수는 빈농 출신이 었고, 만주에서 대개 소작농이나 노동자로 살아갔다. 조선의 빈농은 특히 간도에 대해 ‘영생처’, ‘요지정토’, ‘낙토 이상향’ 등으로 생각하며 이주했다. 항일의식을 가진 조선인은 간도를 ‘조선인의 자유천지’라고 생각하고 이주하였다. 이에 비해 조선총독부 기관지 매일신보는 이주하는 조선인을 ‘생존경쟁 패배자’ 로 간주하였고, 간도에 대해서도 ‘생지옥’ 등으로 표현하며, 이주에 적극 반대하며 만주에 있는 조선인의 귀환을 종용하였다. 그러나 1914년 7월 1차 세계대전의 발발을 즈음하여 매일신보는 조선인의 만주 이주를 ‘일본 대륙경영의 밑바탕’로 간주하기 시작했다. 특히 이듬해 5월 25일 중국과 일본이 ‘남만동몽조약’을 체결한 후부터 매일신보는 지면을 통해 조선인의 만주 이주를 적극 권장하였다. 1910년대 중반 이후 매일신보는 조선인이 만주로 이주하는 것을 ‘고토 회복’에 비유하였고, 나아가 만주와 조선이 불가분리의 관계에 있다고 주장했다. 이는 조선의 경우처럼 만주를 일본의 영토로 삼으려는 대륙침략의 관점에서 나온 것이다. 매일신보의 이런 방침에 협력한 국내 지식인이 장지연이었다. 매일신보와 장지연 및 잡지 반도시론 등은 당시의 만주를 ‘조선인 식민지(殖民地)’로 보았다. 이러한 ‘만주식민지’론은 만주를 항일운동의 근거지로 삼으려는 독립운동을 무산시키려는 담론의 역할을 하였다. 또한 조선인의 만주 이주의 목표를 경제문제의 관점에만 국한시킴으로써, ‘합병’ 이후 경제적 궁핍과 동시에 일제 지배에 대한 불만을 품고 만주로 이주한 조선인의 현실을 왜곡하기도 하였다.

        EDTA의 근관세척효과(根管洗滌效果)에 관(關)한 주사전자현미경적(走査電子顯微鏡的) 연구(硏究)

        이명종,김영해,Lee, Myung-Jong,Kim, Yung-Hai 대한치과보존학회 1983 Restorative Dentistry & Endodontics Vol.9 No.1

        The purpose of this study was to observe the effect of cleansing action of irrigation solutions which was 3% $H_2O_2$ and 5% NaOCl, and 15% EDTA solution on the root canal wall. After treatment with the irrigant, each sample was dehydrated, and coated with 200~250${\circ}$A of gold, and observations were made with the use of scanning electron microscope. The results were as follows: 1. In the root canal walls irrigated with 3% $H_2O_2$ and 5% NaOCl solution without instrumentation after extirpation through barbed broach, the predentin of root canal wall was found scarely affected, and the wall was shown retaining network structure and fibrous organic matters. 2. When 15% EDTA was applied as irrigants for 60, 90 and 120 seconds after instrumentation, there was no signigicant difference of the cleansing effect of the elapsed times which were 90 and 120 seconds on the root canal wall, but in the applied time which was 120 seconds, the canal wall was the cleanest. Therefore it was thought that the most suitable application time of 15% EDTA as the irigants was 120 seconds.

        외국인 직접투자의 경제성장에 대한 영향 : 선진국과 개도국의 비교

        이명종,김석태 한국무역연구원 2012 貿易 硏究 Vol.8 No.4

        The subject This study analyzes the effects that FDl has on economic growth in developed and developing countries. The results of empirical analysis using UNCTD data for the period of 1980 to 2010 show FDI to have generally had a positive influence on economic growth in both developed and developing countries. Based on analysis of developing countries differentiated by income level- high, middle and low-this study finds that, for high-income developing countries, inflows of FDI have had a slightly positive but not so clear effect on economic growth. For middle-income developing countries, FDI is found to have had a significant effect on gross domestic product (GDP), while for low-income developing countries its impacts on GDP have not been significant. This supports the view that, even though FDI flows from developed into underdeveloped countries when conditions such as the recipients' attainments of certain levels of economic growth, exports, and investment are satisfied, the positive impacts on growth are limited due to the host countries' lack of infrastructure and human resources.
