A new application of specrophotometry for the isolation and determination of tertiary base in Corydalis Tuber was investigated. In order to establish the method for isolation and determination of tertiary base in the Corydalis Tuber. Tertiary base was isolated from Corydalis Tuber by organic solvent. When tertiary base was added to a solution containing cobaltous ion and excess thiocyan ion, yellowish-green, 1,2-dichloroethane-solube(base)_2Co(SCN)_4 precipitate. Supportive evidence for identification could be obtained by complexation with tetrathiocyanatocobaltate(Ⅱ) ion. The ultraviolet-visible spectrum of complex vompound in 1,2-dichloroethane exhibits maxima at 282nm and 624nm. The tertiary base was isolated from compex compound and identified as glaucine by UV-Visible spectrum and TLC. A tertiary base in 1,2-dichloroethane scanned from 200nm to 400nm qualitatively exhibits the same absorbance characteristics at identical wavelength as does isolated and concomitantly measured solution of a complex compound. The tertiary base components present in comples compound have been resolved on an absorbance solvent. And it is studied that the differential determination of tertiary base in Corydalis Tuber by spectrophometry. The tertiary base is determined by absorbance of colored products that is produced to reaction of tetrathiocyanatocobaltate(Ⅱ) ion under determination of tertiary base was possible to the range of glaucine 0.100mg/ml-1.000mg/ml in 1,2-dichloroethane. (maximum wavelength; 624nm) The calibration curve showed that the coefficient of variation was 0.9999% for glaucine. Also reproducibility tests showed that the coefficient of variation was 0.9999%. Arepid, specific and precise method using UV-Visible spectrophotometry and TLC has been developed for the isolation and determination of tertiary base in the Corydalis Tuber. The method was applicable to the isolation and determination of tertiary base in Corydalis Tuber or it's extract.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

Considering Characteristics of Meteorologic, ocean graphic at Pusan port and harbour, a mathematical formulation was proposed for the dispersive spreading of spilled oil on the sea. I investigated and certified the application of the theory formulation by comparing the move and dispersion specific of spilled oil which the oil pollution occur in actual, observed on the spot with the theory forecast situation. As the Pusan harbour which is somewhat narrow-in specific of the port and harbour-has a constant wind field in space and has a changeable wind field according to the time. add the wind and current. the vector sum of the surface current and the spreading power of itself-oil, also use a drifter in moving method accoridng to the time, obtained as following conculsion with the results. 1) The major effective factor of the dispersive spreading in spilled oil at Pusan Harbour were as follows: The current effect was larger than that of wind. Both effects were much a larger than that of spreading power. 2) When only the wind force (speed) is over 10 m/s, the wind has a more affection in the poor current area of 0.5 KT bellow more then somewhat. V(σ)=0.03W(σ) + Hd(σ) + A1(σ) 3) According as identifying between the forecast direction of oil dispersive spreading calcualted with the above formulation and the various aspect of the spilled oil investigated actually on the spot until the oil has reached to coast line. The application of the above formulation surveyed and certified. Consider the approved advection symptom after site observed some oil-beyond the directon anticipation are in theory-has mostly reached at coast of the sea. Also think this is reason of irregular current. Warm current spreading and eddy of some port of Pusan.

정치자금 불평등의 수준과 원인

This paper attempts to examine the level of disparity in campaign contributions between an incumbent and a challenger, and find whether the disparity is formed by those who help or invest candidates. Utilizing campaign contributions donated to leadership political committees in the 18th National Assembly elections, this paper unearths the high level of disparity in contributions between incumbents and challengers. The disparity tends to increase when a candidate is a member of a ruling party, has a high level of electability, and runs an election in a regional bloc. This tendency is more evident in small amount of contributions rather than large amount of contributions, thereby asking the review of campaign contribution regulations.

민주시민교육과 투표참여

본 연구는 민주시민교육의 의도된 효과가 현실화될 수 있는지를 분석하는데 목적을 두고 있다. 구체적으로 본 연구는 민주시민교육의 함의인 선거관심도, 선거지식, 그리고 정책적 차별성이 정치 효능감과 투표 효능감에 영향을 미치는 지를 검증하고, 이러한 영향력이 민주시민교육의 궁극적 목적인 투표참여에 있는 지를 분석하는데 목적을 두고 있다. 이러한 목적을 위하여 17대 대통령 선거를 분석한 결과, 기존 연구결과와는 다르게 민주시민교육은 전체적으로 의도한 효과를 거두고 있었다. 그렇지만 민주시민교육의 효과는 세부 내용에 따라 차별적인 효과가 있음이 밝혀졌다. 예를 들어, 민주시민교육의 함의인 선거관심도와 주관적 정책차별성은 투표참여에 긍정적인 영향을 미치고 있었으나, 선거지식은 투표참여에 영향을 미치지 않고 있었다. 이와 같은 경향은 정치 효능감과 투표 효능감에 대한 분석에서도 마찬가지로 나타났다. 따라서 본 연구는 민주시민교육이 투표참여로서 대표되는 정치참여에 긍정적 영향을 미칠 가능성이 크지만, 그 효과는 교육의 내용에 따라 차별적일 수 있음을 지적하고 있다. This study aims at examining whether or not the intended consequences of civic education are embodied. In detail, it attempts to find out whether civic education affects the level of electoral concerns, electoral knowledge, and subjective policy differentiation, thereby increasing the possibility of voter turnout. Utilizing survey data on the 17th presidential election of Korea, it finds out that civic education works, rather in opposite to the existent literature. However, the significance of civic education differs whether one analyzes electoral concerns, policy differentiation or political knowledge. This study concludes, therefore, that although civic education has an influence on voter turnout, its impact will be different in regards to how civic education is taught.

Is a political money scandal an important factor for an incumbent's reelection? When a voter evaluates an incumbent in an election, is a political money scandal considered to be one of key criteria? Since the motivation of an incumbent is to be reelected, it is a reasonable assumption that he or she observes money ethics. However, political money scandals have not rarely been seen. The discrepancy between the reasonable assumption and the frequent money scandals is needed to pay attention. This paper aims to solve this puzzle, using the U.S. Senate elections of 1998 and 2002. The year of 1998 was the year when the Enron scandal, which was the most salient political money scandal in the late twenty century, was not exposed, while the year of 2002 was the year when it was exposed to the people. The findings suggest that the political money scandal neither affected an incumbent's reelection nor played any role of voters' evaluation. This paper strongly suggests that a new institutional mechanism should be installed for preserving money ethics.

상황인식 기술을 적용한 도시철도 지능형 감시시스템에 관한 연구

엄기열(Ki-Yeol Eom),홍다혜(Da-Hye Hong),강민구(Min-Gu Kang),안태기(Tae-Ki Ahn),김문현(Moon-Hyun Kim) 한국지능시스템학회 2008 한국지능시스템학회 학술발표 논문집 Vol.18 No.2

최근 도시철도 역사 내의 범죄 및 테러 등과 같은 주변상황을 감시하거나 초기에 인식하고 대처하기 위해 각종 센서와 영상 감시 카메라의 설치 및 사용이 증가하고 있는 추세이다. 하지만, 이러한 감시 시스템은 관리자가 직접 검토하고 판단해야하는 불편함이 있다. 이러한 단점을 개선하기 위해 본 논문에서는 상황인식 기술을 이용한 지능형 감시시스템을 제안한다. 지능형 감시 시스템이란, 영상카메라에서 얻은 디지털화된 정보를 이용하여 사전에 정의된 패턴분석 규칙에 따라 사용자 및 환경상황, 패턴을 분석하고 사고 및 이상 징후가 발생할 경우 스스로 판단하여 경보 및 차단 시스템을 작동 시키는 시스템을 말한다. 제안된 시스템은 철도 역사 내에서 획득한 상황 데이터와 시스템 내의 미리 정의 된 규칙과의 비교연산을 수행한 후 시스템 스스로가 현재 상황에 적합한 대응책이나 결과를 추론하는 지능형 감시시스템이다.

This paper attempts to examine the effect of school ties when a party nominates its candidates in Korea. In particular, a high schol and/or a university tie between an interviewer and an interviewee are faced with empirical analyses in mayoral elections. Among people, it has been alleged that cronyism, specifically a school tie, affects party nomination. Utilizing mayoral elections, we try to examine this notion. Empirical findings suggest, however, that it might not be a reality. Whether to examine a high school tie, a university tie, or both cannot reach a statistical significance. It suggest the same findings when analyzing all parties, major parties, Hanara Party or Minju Party. Therefore, we conclude that at least a school tie, one of the Cronyism types, does not play a large role when it comes to party nomination.
