메탄올-물 혼합용매 및 수용성 CTAB, SDS 용액에서 2-에틸안트라센[2-EA]과 9-페닐안트라센[9-PA]에 빛을 조사하는 동안 1,3-디페닐이소벤조푸란[DPBF]이 감소되는 것으로부터 이 반응에 단일항 산소$(^1O_2)$가 관여된다는 화학적 증거를 얻었다. 용매의 극성에 민간함 UV 분광학적 특성을 이용하여 2-EA와 9-PA의 평균미세환경의 극성을 조사하였다. 2-EA와 9-PA가 수용성 CTAB, SDS 및 Brij 35 용액에 가용화될 때 그들의 평균 미세환경은 극성이었으며, 미세환경의 극성 파라미터는 미셀의 이온성에 영향을 받지 않았다. 2-EA의 평균 미세환경의 극성은 40%(w/w) 에탄올 수용액의 극성과 비슷했으며, 9-PA의 경우는 30%(w/w)와 40%(w/w) 사이의 에탄올 수용액의 극성과 비슷했다. 이들 화학종들이 수용성 미셀용액에 가용화될 때 대부분 미셀의 표면에 분포할 것이라는 것을 알았다. 여러 용매에서 2-EA와 9-PA의 광증감능을 검토하였다. 메탄올-물 혼합용매가 수용성 미셀용액보다 광산화반응에 유리한 것으로 나타났다. The chemical evidence for involvement of singlet oxygen during photoirradiation for 2-ethylanthracene [2-EA] and 9-phenylanthracene [9-PA] was based on the rapid decomposition of 1,3-diphenylisobenzofuran [DPBF] in methanol-water mixture and aqueous CTAB, and SDS micellar solutions. The average microenvironmental polarities of 2-EA and 9-PA were estimated by UV spectroscopic characteristics sensitive to the polarity of solvent. When 2-EA and 9-PA were solubilized in aqueous CTAB, SDS and Brij 35 solutions, their average microenvironmental polarities were polar, and their microenvironmental polarity parameter showed little dependence on the ionic properties of the micelles. The average microenvironmental polarity of 2-EA was similar to the polarity of 40% (w/w) aqueous ethanol, and that of 9-PA was similar to the polarity between 30 and 40% (w/w) aqueous ethanol. It was found that the greater part of these species might be distributed at the surface of micelles when they were solubilized in aqueous micellar solutions. The methanol-water mixture solution appeared to have characteristics more favorable for photooxidation reaction than aqueous micellar solutions.

고정수,원형중 한국골프학회 2010 골프연구 Vol.4 No.2

This study aimed at figuring out the level of importance and the order of priority of the factors (the instructional ability, physical conditions, attitudes and career) golfers were satisfied with regarding a golf instructor through an AHP analysis. In order to achieve the aim, a survey was conducted involving 100 golfers sampled from the golfers using a golf range in Seoul. Of the collected questionnaires, 28 were excluded due to their inconsistency in the AHP analysis and the other 72 questionnaires were subjected to the analysis. Through these procedures, the following conclusions were acquired. First, the relative level of importance and the order of priority of the factors the golfers were satisfied with regarding a golf instructor are as follows. To begin with, when it comes to the level of importance of the factors, the instructional ability, attitudes, career and physical conditions were placed in order of decreasing importance. Second, depending on demographic factors, the relative level of importance and the order of priority of the factors the golfers were satisfied with regarding a golf instructor are as follows. To begin with, as for the level of importance of the factors, both male and female golfers, regardless of gender, put the instructional ability, attitudes, career and physical conditions in order of decreasing importance. Based on the results above, the researcher found the relative level of importance and the order of priority of the factors golfers were satisfied with regarding a golf instructor. Golfers valued an instructor's instructional ability the most while attaching relatively less importance to his physical conditions. In addition, depending on the demographic features and playing features of golfers surveyed, the order of priority of the sub-factors the golfers were satisfied with regarding a golf instructor was different. This indicates that a more flexible and realistic alternative that considers customers should be presented.

고정수,동정근 대한건축학회 2001 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.21 No.2

This thesis investigates the logics of form as the tendency of artificial landscape in post avant-garde architecture. The initial question of this research is how the new stream different from the previous, on the way that relate architecture to the landscape, we suspect common theory, which shares the nonlinear, indeterminent and wholness. and we identify the landarc, which is becomming a main stream in post avant-garde. The purpose of report is to make clear what are the meaning of elements composite form and the way of expression that is a characteristic of artificial landscape as a experiential space.

수용성 미셀용액에 가용화된 mesityl oxide 및 N-nitrosodimethylamine의 미세환경의 성질에 관한 연구

高正秀 木浦大學校基礎科學硏究所 1985 基礎科學硏究誌 Vol.3 No.-

The UV spectra of mesityl oxide and N-nitrosodimethylamine in various solvents and aqueous micellar solutions were measured. The site of solubilization and the nature of the microenvironments were found to be dependent upon the nature of the solubilizates rather than upon that of the solubilizers. The n→π* Transitions for mesityl oxide in the micelles were observed in low polar environment while those for N-nitrosodime-thylamine in high polar environment.

미셀계에 있어서 용해성 화학종의 미세환경에 관한 연구(II) : 수용성 미셀용액에 가용화된 phenanthrene의 미세환경의 성질 The Nature of the Microenvironment of Phenanthrene Solubilized in Aqueous Micellar Solutions

高正秀 木浦大學校基礎科學硏究所 1984 基礎科學硏究誌 Vol.2 No.-

The average polarities of the microenvironment of phenanthrene solubilized in the aqueous micellar solutions containing cetyltrimethylammonium broumide, sodium lauryl sulfate and polyoxyethylene (23) lauryl ether as micellar forming surfactants were measured by the UV absorption spectra. Phenanthrene is solubilized in near surface part of micelle. The polarity of the microenvironment of phenanthrene is not depend upon the ionic characteristics of surfactants, and higher than that of anthracene.

기상 모델에서 구름미세물리모수화 방안은 지표에 도달한 눈, 싸라기 (혹은 우박), 비의 혼합비를 강수의 단위로 변환하여 격자규모의 강수를 예단한다. 본 연구에서는 4개의 벌크형 이중모멘트 구름미세물리 모수화 방안(Weather Research and Forecasting (WRF) Double-Moment 6-class (WDM6), WRF Double-Moment 7-class (WDM7), Thompson, Morrison)을 이용하여 겨울철 강수 사례의 대기수상의 혼합비 모의에 대한 각 모수화 방안 내 상세 미세물리과정들의 상대적 기여도를 제시하고자 한다. 또한 모의된 혼합비를 관측된 분포와 정성적으로 비교하고자 한다. 4개의 모수화 방안 모두 비상의 혼합비는 융해과정에 의해 주로 생성되었다. 구름방울의 경우 WDM6와 WDM7 방안은 핵화 과정에 의해서 주로 생성되었으며, 증발에 의해 소멸되었다. Thompson과 Morrison 방안은 주로 응결에 의해 구름방울이 생성되었으며, 눈 혹은 비와의 충돌에 의해 소멸되었다. 얼음 입자의 생성 및 소멸에 관여하는 상세 물리과정을 분석한 결과 Thompson 방안에서는 침적 과정과 눈으로의 자동 전환 과정이 주요한 얼음 입자 생성 및 소멸 과정으로 분석되었다. 그 외의 방안들에서는 핵화 과정과 침적 과정으로 얼음 입자가 주로 생성되고 눈으로의 자동 전환과 눈과의 충돌 과정으로 얼음입자가 소멸하는 것으로 분석되었다. 다른 방안에 비해 얼음 입자가 많이 만들어지는 WDM6와 WDM7 방안에서 눈은 얼음 입자의 소멸을 통해 생성되었지만, 얼음 입자가 상층에만 존재하는 Thompson과 Morrison 방안에서 눈의 생성은 주로 구름방울과의 충돌에 의해 발생하였으며, 소멸은 융해 과정에 의한 것으로 분석되었다. Thompson을 제외한 구름미세물리 모수화 방안에서 싸락눈의 생성은 눈 혹은 싸락눈과 구름방울의 충돌에 의해 발생하였으며, 융해 과정으로 싸락눈이 소멸하였다. 우박의 혼합비를 예단하는 WDM7의 경우 싸락눈과 우박의 충돌과정으로 인해 대부분의 우박이 생성되는 것으로 분석되었다.

Third, the frequency of participation in golf, is less than or equal to 10 times, deadlines, while important, expressive, 11-20 times a leadership and motivation, at least once every 21 to 30 showed that more important. Fourth, in a round of golf experience, availability, non-beginners any physique condition, important deadlines,while Microscope-experienced important than the aesthetic criteria that appear to be better. Fifth, the golf handicap, 11-20 handicap is only noticeable difference, the leader's satisfaction is more important in the leadership and found that eligibility.
