김유선,오정희,Kim, Yoo-Sun,Oh, Jung-Hee 대한화학회 1967 대한화학회지 Vol.11 No.4

Various amines (Triethylamine, Diethylamine, Dimethylaniline, Pyridine and Diphenylamine) and electron acceptors (Carbontetrachloride, iodine monochloride and iodine) were reacted in the hexane solvent system to form a charge transfer complex in each case. The tendency of forming a charge transfer complex by these electron acceptors was proportional to the basicity of amines and the different type of complex was formed as the polarity of electron donor had markedly changed, which were identified by ultraviolet spectrophotometry. A correlation between the formation of complex and the basicity of amine and the polarity of electron acceptor was discussed. 各 種 아민(triethylamine, diethylamine, pyridine, diphenylamine, dimethylaniline)과 各種 Electron Acceptor($CCl_4,\;ICl,\;I_2$)를 Hexane 溶媒 存在下에서 作用시킨 結果 各各 Charge Transfer Complex를 形成하였으나 그 形成能은 아민의 Basicity에 比例하였고 Electron Donor의 Polarity의 差가 클 때에는 다른 形式의 Complex를 形成함을 紫外線 吸收 分光法으로 確認하였다. Complex 形成能과 아민의 Basicity 및 Electron Acceptor의 Polarity의 關係를 論하였다.

김유선,오정희,Kim, Yoo-Sun,Oh, Jung-Hee 대한화학회 1967 대한화학회지 Vol.11 No.4

The formation of a charge transfer complex between various amines and organic halogen compounds was closely investigated. A mixture of amine (piperidine, pyridine, diethylamine, ethylamine, triethylamine and triethanolamine) and organic halides(carbon tetrachloride and chloroform) was checked for its UV absorption spectrum in presence of n-hexane solvent. A red shift was observed. The formation of charge transfer complex was observed in the case of triethylamine and diethylamine, whereas the formation of contact complex was distinct in case of piperidine. The relation between the nucleophilicity of amines and their tendency of forming charge transfer complex was discussed. 各種 아민과 할로겐化合物間의 Charge Transfer Complex 形成與否를 檢討하여 보았다. Pyridine Tridthylamine, Piperidine Ethanolamine Triethanolamine, Aniline, Diethylamine 等의 아민類와 四鹽化炭素 또는 클로로폼의 混合溶液을 n-Hexane 溶媒存在下에서 紫外線吸收 스펙트라를 檢査한 結果 장파장쪽의 Shift가 있었으며 特히 Diethylamine과 Triethylamine은 클로로폼 또는 四鹽化炭素와 1:1 Charge Transfer Complex를 形成하였고, Piperidine은 接觸的 Complex를 形成하는 것이 確認되었다. Complex의 形成경향과 아민의 Nucleophilicity와의 關係를 論議하였다.

In this study, we comparatively analyzed the preference of pattern foliage plants to provide the basic data for the status of current use of pattern foliage plants by researching and analyzing changes in the preference of such plants in the years 2010 and 2020. We also analyzed the color-harmonious beauty of pattern foliage plants currently distributed in the market. This study targeted 18 species used for a survey on the preference of pattern foliage plants, and eight species of pattern foliage plants in 2020. For the research and analysis of preference, three surveys were conducted. For the measurement of plant color, the plants were domesticated in a greenhouse (shading rate: approximately 40%) for a week. After taking a photograph of each individual plant in a light room on the basis of day light, the color was measured by correcting it to a standard color using the Adobe Photoshop Program. The results of analyzing the preference of pattern foliage plants using the above method were as follows. Firstly, it was clear that the preference of green-patterned plants was higher than that of red-patterned plants. Secondly, in the plants with red and yellow patterns, the preference was low when the brightness difference was larger. In plants with the same green patterns, the preference was shown regardless of the brightness difference. Moreover, when the difference in chroma was greater, the preference was low. Thirdly, color had the highest influence on the preference of plants. In the case of pattern plants with the same group of colors, the form of pattern and color arrangement rate had a higher influence on the preference than color. As the preference of plants is different at different times, and the preference should be quickly understood to use it for marketing strategies, there should be continuous research on the preference of plants in the future.

소비자의 기호에 맞는 품종 개발을 위해 필요한 요소 중 꽃의 대표적 미의 상징인 화색을 분석하여 색채 팔레트를 구성하고 이를 이용할 수 있도록 국내 장미색채를 조사ㆍ분석한 결과 다음과 같았다. 국내 절화장미를 대상으로 2010년 4월부터 2011년 3월까지 12개월 동안 서울 고속버스터미널 3층에 위치한 화훼시장에서 1달에 1회 총 12회 방문하여 그 시기에 나온 모든 장미를 수집하였고 수집된 120개의 품종을 먼셀 10색상을 이용하여 육안분류 후 분류된 장미를 다시 RHS (Royal Horticulture Society) color chart를 이용하여 육안분류하였다. 그 후 분류된 장미를 색측기(X-rite Eye-One Xtreme iO bundle)로 측색 후 그 값으로 색채칩을 만들었다. 만들어진 색채칩을 다시 먼셀 10색상으로 분류하여 색채 팔레트지 구성하였는데 전체 절화장미의 색채에서는 Red Purple이 36.8%로 가장 높은 비율을 차지하였고 Green Yellow와 White가 4.2%로 가장 낮은 비율을 차지하였으며 Green, Blue Green, Blue, Purple Blue 색채는 존재하지 않았다. 각 절화 장미의 꽃잎 색채에서는 Red Purple이 25.5%로 가장 많은 분포를 보였고 큰 차이 없이 Yellow가 24.9%로 두 번째로 많은 분포를 보였다. Purple이 4.8%로 가장 낮은 분포를 보였다. 위와 같은 분석을 통해 210개의 색채가 들어있는 팔레트를 구성하였으며 이는 절화 장미 품종개발 뿐만 아니라 더 넓은 분야에서 이용될 수 있을 것이라 기대된다. 또한 활발한 색채 팔레트의 이용과 활용을 위해서는 계속적인 팔레트 구성과 분석이 이루어져야 할 것이라 생각된다. This paper aims to compose and use the color palette that was analyzed floral color to develop diversity of plans for customer’s choice. The result of research and analysis of cut-flower roses in domestic flower markets is following. 120 kinds of inland cut-flower roses were collected in flower market on third floor of Seoul Express Bus Terminal during 12 months, from April, 2010 to March, 2011. After it, This study was classified under Muncell’s 10 hue. And it was sorted again using by RHS(Royal Horticulture Society) color chart. Thereafter, color chips that measured by a color measuring instrument called X-rite Eye-One Xtreme iO bundle had made. Color chips what had made were sorted again with Muncell’s 10 hue and composed a color palette of cut-flower roses. The highest ratio in all kinds of color of roses is Red Purple (36.8%). And the lowest proportion are Green Yellow and white which is 4.2%. In case of Green, Blue Green, Blue, Purple Blue were nonexistent there. On the other hands, The highest dispersion in each leaf color of cut-flower roses is Red Purple (25.5%) and Yellow is next. it has 24.9%. But Purple is 4.8%. It means that it has the lowest. Due to the study as above, the palette that had made by 210 kinds of color of cut-flower roses in domestic were composed to improve varieties of cut-flower rose. In addition, The purpose of this thesis is to use it in many ways. At the conclusion, this analysis and composing the color palette of cut-flower roses in domestic market will be kept for the active utilization of color palette.

주 40시간 근무제가 노동자 여가생활에 미친 영향

김유선 ( Yoo Sun Kim ) 한국산업노동학회 2011 산업노동연구 Vol.17 No.1

통계청의 ``경제활동인구조사 부가조사``(2010년 3월)와 문화체육관광부·통계청의 ``국민여가활동조사``(2010년 7월)를 분석한 결과, 주40시간 근무제가 노동자들의 근로시간과 여가생활에 미치는 영향은 다음과 같다. 첫째, 주40시간 근무제는 실 근로시간을 11.3% 단축시키고, 장시간근로 확률을 1/5로 축소시킨다. 시간당 임금에 대한 근로시간 탄력성은 -0.145로, 임금이 낮을수록 실 근로시간이 길고 장시간근로 확률이 높다. 저임금과 장시간근로는 동전의 양면이다. 둘째, 주40시간 근무제는 휴일 여가시간을 매개변수로 하여 여가비용에 영향을 미친다. 휴일 여가시간이 10% 늘면 여가비용이 3% 늘어난다. 주40시간 근무제는 스포츠 등 적극적 여가활동을 늘리고, 자원봉사, 동호회 등 사회성 여가활동에 긍정적 영향을 미치고 있다. 셋째, 주40시간 근무제 이후 생활에서 나타난 가장 큰 변화로는, 10명 중 7명이 ``가족과 함께 하는 여가시간 증가``(52.2%), ``자기 계발을 위한 시간 증가``(l5.7%) 등 긍정적 변화에 응답하고, ``여가 소비지출 부담 증가``(6.3%), ``수입 감소``(3.4%) 등 부정적 변화는 13.9%, ``별다른 변화 없음``은 14.4% 응답했다. 긍정적 생활변화는 여가생활 만족도 증가로 이어지고 있다. 넷째, 다른 변수를 통제하더라도 주40시간 근무제는 주관적 행복수준에 직접 영향을 미칠 뿐만 아니라, 여가생활 만족도를 매개변수로 하여 간접적으로도 영향을 미치고 있다. 따라서 주40시간 근무제가 노동생활과 여가생활에 미친 영향이 긍정적이라는 사실을 분명히 인식하고, 빠른 시일 내에 모든 직장에 주40시간 근무제가 정착되도록 가능한 모든 노력을 기울여야 한다. 주40시간 근무제를 5인 미만 사업장으로 확대하고, 초중등학교에 주5일 수업제를 전면 실시하고, 적극적 여가활동 여건을 조성해야 한다. 근로감독 행정을 강화해서 주 52시간을 초과하는 탈법적인 장시간근로를 제한하고 저임금을 일소해야 한다. The 40-hour work week system has brought positive impact on shortening working hours, eliminating long-time work, increasing leisure-tint with family, etc. And this has brought about an increase in leisure-life satisfaction and happiness level. The type of leisure activities has changed from passive activities such as rest to active activities such as sports, tourism. And the 40-hour work week system has positive impact on social activities such as participation in volunteer work and, club activities. This all efforts need to be made to establish 40-hour work week system as soon as possible in all workplace. Firstly, 40-hour work week system needs to be introduced to every workplace with less than 5 persons, enlarge 5-day school week system into every primary and secondary school, and create conditions for positive leisure activities. Secondly, labor standards supervision and administration needs to be strengthened to eliminate long-time work over 52 hours par week, below-mininum wage work.

최저임금의 고용효과

김유선 ( Yoo Sun Kim ) 한국산업노동학회 2014 산업노동연구 Vol.20 No.3

이론과 실증분석 두 측면에서 선행연구 결과를 살펴본 뒤, OECD 25개 회원국(1990~2012년)에서 최저임금의 고용효과를 추정했다. 분석결과는 다음과 같다. ‘국가별 이질성을 통제한 상태에서 OECD 회원국에서 최저임금의 고용효과를 분석하면, 최저임금 인상이 전체 고용과 여성 고용, 고령자 고용에 미친 부정적 영향은 발견되지 않는다. 그러나 청년 고용에 미친 영향은 분석모형에 따라 유의도가 엇갈려 뚜렷한 결론을 도출할 수 없었다.’ I looked into the results of preceding research and estimated the employment effect of minimum wages among 25 OECD member countries between 1990 and 2012. The analysis results are as follows, “the negative effect of minimum wages on total employment, women employment and aging senior employment is not found. But, as the effect on youth employment missed each other, depending on analysis model, I failed to draw any definite conclusion.”

김유선(Kim Yoo-Sun) 고려대학교 아세아문제연구소 2006 亞細亞硏究 Vol.49 No.3

This study analyzes the determinants of the increase in strike activity following the 1997 economic crisis, through a time-series analysis from 1975 to 2005. The findings of the analysis can be summarized as follows: the rising of the trade dependence, the worsening of the labour share of income and the increasing of the unfair labor practice were responsible for propelling the increases in strike activity since 1998. The results of the study point to a policy implication : the centralization and coordination of the industrial relations system, the improvement in income distribution, and the supervise of the unfair labor practice would be vital in easing the intensity of industrial conflicts and bringing down the incidences of strikes.

김유선(Kim Yoo-Sun) 고려대학교 아세아문제연구소 2004 亞細亞硏究 Vol.47 No.1

This paper analyzes the structural changes, more specifically, nonstandard workforce increase, in the Korean labor market after the exchange rate crisis. Both labor market flexibility and wage inequality are increasing very rapidly, and surpassing them found in the American labor market after the exchange rate crisis. In this paper, some conventional hypotheses which focus on the labor market factors as the causes of nonstandard workforce increase the demographic changes in the labor force composition, the changes in the economic environment, nonstandard workforce as a buffer for the protection of core workers, the changes in the industrial structure-are rejected. In contrast, this paper supports the hypotheses to focus on actor-related factors such as the changes in the human resource management strategy, the labor market flexibility policy of the government, and the diminished bargaining power of the labor by providing empirical evidence.
