In last pereod of Goryeo(高麗) dynasty, Myeong(明) dynasty cared Goryo dynasty conspires with a Bugwon(北元) force and closed Ryaotung(遼東) for efficient control about Goryo dynasty. Therefore the envoy of that time only chose the sea route. But Gwon, Geun(權近) went to Bcijing(北元) vicinity and entered Nanjing(南京) through the canal and came back home through the sea route in 1389. Gwon, Geun returned with the letter of Myoung Emperor at that time. This letter's possibility to be forged is big. Gwon, Geun must keep the discussion about enthronement of king really and dethronement of imitation king(廢假立眞) by this letter. Therefore he could not choose long land route which the period takes. The 『Bongsalog(奉使錄)』 of the Gwon, Geun is the content of the course which start in June 1389 and comes back to September 1389. He described a that time circumstances of the Myeong dynasty so that he was quite minute. A minute description of the Gwon, Geun was the purpose to grasp the circumstances of the Myeong dynasty. In the envoy poetry Jeong, Mong-Ju(鄭夢周) and Gwon, Geun expressing the international relation of that time in the world which to be unified around the Myeong dynasty to be unified. But Nahachu(納哈出) did not surrender when the Jeong, Mong-Ju went to the envoy. Therefore Jeong, Mong Ju recognized the international relation of the day to a military confrontation relation. And Myeong dynasty wish excessive requirement. And there is so many restriction in the route which the envoy goes. Therefore Jeong, Mong -Ju did not think about the Myeong dynasty so that it was good. Nahachu surrendered when Gwon, Geun went to the envoy. And he could go through the Ryaotung. Therefore he thought about the Myeong dynasty so that it was very good. And he expressed very much north races including the Bugwon so that he was humble. This is the direct opposition with his thought about the Myeong dynasty. We can know in his such expression that he is familiar with the Myeong dynasty and disliked the Bugwon.

Microsporum (M.)canis 감염은 애완용으로 기르는 고양이나 개가 주된 감염원이며 두부 백선, 안면백선 및 체부 백선 등의 피부질환을 일으킨다. 특히 M. canis 가족감염예는 M. canis 감염증중 비교적 드물다. 저자들은 전형적인 임상 및 균학적 양상을 보인 고양이로부터 감염된 M. canis 가족예를 경험하고 문헌고찰과 함께 보고한다. Microsporum canis Infections Occurring in a Family Departments of Dermatology & Clinical Pathology, College of Medicine, Dongguk University Moo Kyu Suh M.D., Yeol Oh Sung M.D., Ki Seong Yoon M.D., Gyoung Yim Ha M.D." We report a case of Microsporum (M.) canis infections occurring in a family. The mother, a son and a daughter had multiple, wen defined, round, scaly erythematous patches on the scalp & face, face & trunk, and face & chest respectively. Culture from skin lesion of patients and an infected kitten on Sabouraud dextrose agar showed M. canis. After 15 days to one month administration of itraconazole, the lesins healed leaving a slight hypopigmentation.

效率的 市場假設에 關한 理論的 考察

崔璟植 청주대학교 대학원 1988 우암논총 Vol.4 No.-

Recently we are concerned with the Efficient Capital Market Hypothesis(EMH) that evaluates the potential usefulness of accounting system through empirical study on accounting- information-users' claim for informations or their decision- making- behaviors. EMH is a theory that explains the relationship between accounting informations and security prices, on the ground of the hypothesis that the market for securities is efficient if security prices reflect full and promptly(instaneously) al1 available informations. The main purpose of this paper is four. First is to discuss the concept and the theoretical back-ground of EMH. Second is to examine the three model of the EMH- that is, randomwalk model , martingale- submartingale model and expected return model. Third is to investigate the three forms of efficiency verification that is ,weak form, semi -strong form and strong form of the EMH-, and to consider the empirical evidences on semi -strong form of the EMH that is the most important and has accounting significance. Fourth is to study the limitation of the EMH theory at three sides that is, the ambiguity of definition of the EMH, the impropriety of precondition of the EMH and R.G. May & G. L. Sundem's opinion.

Recently Excessive national resources, energy losses and social·economical problems are induced by reconstruction apartment housing which was constructed about 20 years and is enough to keep one's residence structurally. Especially, the greatest obstruction in longevity & recycling technology of apartment housing is the current Ondol system of wet process integrated structures. Also the current Ondol system is difficult to improve due to its character of material and process. The object of this study is to develop IHCS(Infill Heating & Cooling System) standard model with prefabricated & dry process that shall be the substitution for the current wet Ondol system.

퍼지 입력표현방식을 갖는 오류역전파 신경회로망 모델

In this paper, we propose a neural network with fuzzy input signal representation scheme not only for improving the classification accuracy but also for being able to classify objects whose attribute values do not have clear boundaries. The fuzzy input signal representation scheme is included as a preprocessing module. It transforms imprecise input in linguistic form and precisely stated numerical input into multidimensional numerical values. The transformed input is processed in the postprocessing module. The experimental results indicate the superiority of the backpropagation network with fuzzy input signal representation scheme in comparison to the conventional backpropagation network.

딕카이트로부터 스멕타이트의 수열합성

류경원,장영남,배인국,채수천,최상훈 한국광물학회 2004 광물과 암석 (J.Miner.Soc.Korea) Vol.17 No.3

딕카이트[Al₂Si₂O_(5).(OH)₄]를 출발물질로 사용하여 이팔면체형 스멕타이트를 수열합성하였다. 시료를 활성화시키기 위해 Na₂O 성분을 첨가하고 800℃에서 4시간 열처리하였다. 합성실험을 Na-0.7 바이델라이트의 화학반응식에 의한 화학양론적 조성에 따라 SiO₂성분을 첨가하였으며 300℃, 70 ㎏f/㎠ 이하의 조건에서 온도, 압력, 시간 등을 변화시키면서 실험을 수행하였다. 합성실험을 위해 약 1리터 용량의 밀폐형 강철재 압력용기를 사용하였다. 스멕타이트를 합성할 수 있는 최적 조건은 반응온도 290℃, 반응시간 48시간, pH 10 및 60 ㎏f/㎠ 의 압력조건인 것으로 확인되었다. 온도, 압력조건 외에 원료물질의 활성화, 반응시간, 반응용액의 초기 pH 등은 결정도에 영향을 미치는 주요 요인으로 작용하였다. 합성결과물에 대한 X-선 회절분석, 에틸렌글리콜 처리, 'Greene-Kelly' 측정법 등의 실험결과, 합성된 스멕타이트는 Na-바이델라이트임이 확인되었다. A hydrothermal process was used to synthesize dioctahedral smectite from dickite [Al₂Si₂O_(5).(OH)₄]. Dickite was previously activated by heating at 800℃ for 4 hours with Na₂CO₃. After the heat-treatment, Sift was added for stoichiometrv. The autoclaving was carried out in closed stainless steel vessel (about 1 liter) at the condition of various temperature, pressure, time etc. High quality smectite could be obtaind by heating at 290℃ under the pressure of 60 ㎏f/㎠ for 48 hours. This experiment reveals that pH of the solution was an important factor and should be maintained at 10 to 11 for the formation of dioctahedral smectite. Be synthesized smectite was identified as Na-beidellite by the treatment of ethylene glycol and Greene-Kelly test.

두 종류의 ZnSe 분말을 사용하여 sublimation 방법으로 성장한 ZnSe 단결정(as grown)에 대하여 TSC와 TSL을 동시 측정하였으며, PL과 DLTS를 측정하였다. PL 측정으로 I_1, I_2와 DAP 발광을 관측하였으며 DLTS에 의한 깊은준위를 관측하였다. TSL과 TSC의 동시 측정으로부터 얻은 그로우 곡선을 점근 해법으로 분해하여 세개의 준위를 얻었으며 그들의 활성화에너지값은 0.22 eV, 0.30 eV, 0.39 eV이었다. PL spectrum과 열자극 완화과정의 동시 측정 결과로부터 0.22 eV 근방에 impurity에 의한 주게준위와 native defect에 의한 받게준위가 각각 전도대의 아래와 가전자대의 위에 존재하는 것으로 판명되었다. DLTS 측정과 동시측정 결과로부터 0.30 eV와 0.39 eV의 준위는 V_se vacancy와 관련되는 주게 준위임을 알았다. Simultaneous measurements of TSL were carried out on ZnSe single crystals grown by high pressure Bridgman technique and the PL and DLTS signals were observed. Photoluminescence spectrum at 10 K on the ZnSe crystal reveals I_1 and I_2 lines, as well as DAP emission line. DLTS spectrum on the ZnSe crystal show electron trap at 0.33 eV. Two TSC and TSL peaks were observed near 215 K and 230 K, which are identified as having originated from two donor trap levels at 0.30 eV and 0.39 eV, respectively, below the bottom of the conduction band. We also observed single TSL and TSC peaks at 150 K which were identified as having originated from a donor and acceptor trap levels at about 0.22 eV below the conduction band and over the top of the valence band, respectively.
