자동차 폐촉매의 침출액으로부터 백금족 금속의 분리를 위하여 용매추출에 대한 기초연구가 수행되었다. 추출제로 tri-n-butyl phosphate (TBP), tri-n-octylamine (TOA) 그리고 di-n-hexyl sulfide (DHS)를 등유에 희석하여 사용하였다. 추출제의 종류 및 농도가 백금, 팔라듐 그리고 로듐의 추출거동에 미치는 영향을 조사하였다. 또한 세륨, 납, 철, 마그네슘 그리고 알루미늄 등 침출액에 존재하는 주요 금속불순물의 추출거동도 함께 조사하였다. TBP는 백금과 팔라듐, 그리고 TOA는 백금, 팔라듐, 로듐을 동시에 추출하였다. DHS 추출제인 SFI-6에 의한 용매추출 시 백금이 팔라듐과 함께 유기상으로 추출되었으나, SFI-6R은 팔라듐만 선택적으로 추출하였다. SFI-6R은 SFI-6에 비하여 팔라듐에 대한 선택성이 우수하였으나 추출속도가 느렸다. 추출제의 종류에 따라 백금족 금속과 함께 추출되는 금속불순물들이 달라지며 세정 또는 탈거공정에서 이들을 제거하여야 한다. 자동차 폐촉매의 침출액으로부터 백금, 팔라듐 그리고 로듐을 분리하기 위하여 먼저 DHS 추출제인 SFI-6R를 사용하여 팔라듐을 분리한 다음 TBP 또는 TOA으로 백금을 추출하여 로듐과 분리하는 공정이 적절한 것으로 나타났다. The solvent extraction for the separation of platinum group metals from the leach liquor of spent automotive catalysts has been studied. Tri-n-butyl phosphate (TBP), tri-n-octylamine (TOA) and di-n-hexyl sulfide (DHS) were used as extractants and kerosene as a diluent. The extraction behavior of platinum, palladium and rhodium has been investigated as functions of different kinds of extractants and their concentrations. In addition, the extraction behavior of the major metal impurities such as cerium, lead, iron, magnesium and aluminum has been investigated. Platinum and palladium were extracted with TBP. And platinum, palladium and rhodium were extracted with TOA. Platinum was co-extracted with palladium into the organic phase by solvent extraction using SFI-6 of DHS extractant, but only palladium was selectively extracted with SFI-6R. The selective extraction of palladium with SFI-6R was found better than that with SFI-6, but the kinetics of extraction with SFI-6R was found poor in comparison to SFI-6. The metal impurities extracted simultaneously during the extraction of platinum group metals should be removed in scrubbing and stripping processes. A suitable process has been proposed for the separation of platinum group metals from the leach liquor of spent automotive catalysts. Initially palladium was extracted with SFI-6R, followed by the separation of platinum with TBP or TOA leaving rhodium in the raffinate.

한국땅거미 ( Atypus coreanus Kim. 1985 ) 전대그물의 화학적 정량분석

김주필,이영보,장승종,김미애 ( Joo Pil Kim,Young Bo Lee,Seong Jong Jang,Mi Ae Kim ) 한국환경생물학회 1998 환경생물 : 환경생물학회지 Vol.16 No.1

Spiders are easily distinguished from all other creatures by behavior of making webs. Among the web building spiders which depend largely on their webs to predation, Atypidae, four species in Korea, uses the purse web which is the most primitive one than other spider`s web in Korea. To analyze the chemical properties of the purse web, 30 ㎎ of Atypus coreanus` web was collected in Joan-myun, Namyangjoo-city, Kyunggi-do. As a result, the purse web of Atypus coreanus mostly consists of Glycine (5.3%), Glutamic acid (8. 26%) and Alanine (14. 17%). Especially the web of Atypus coreanus has more proportion of serine (9.28%), which plays an important role in intricacy, than that of orb webs used by Nephila clavata(4.84%) and Araneus ventricosus(4.84%).

셰익스피어의 오도된 재현과 욕망

김미애(Mi-Ae Kim) 한국셰익스피어학회 2011 셰익스피어 비평 Vol.47 No.3

Although the human conscience and its functions have been variously interpreted and although the ways of moralists, theologians and psychologists part when the provenance and the nature of the norms to which conscience is bound are at issue, there is a fundamental agreement as to the reality and significance of this mental faculty. It is full of sweetness and pleasantry. It is perhaps too good-natured for comedy. It has little satire, and no spleen. It aims at the ludicrous rather than the ridiculous. It makes us laugh at the follies of mankind, not despise them, and still less bear any ill-will towards them. Shakespeare's comic genius resembles the bee rather in its power of extracting sweets from weeds or poisons, than in leaving a sting behind it. There is a certain stage of society in which people become conscious of their peculiarities and absurdities, affect to disguise what they are, and set up pretensions to what they are not. This gives rise to a corresponding style of comedy, the object of which is to detect the disguises of self-love, and to make reprisals on these preposterous assumptions of vanity, by marking the contrast between the real and the affected character as severely as possible, and denying to those who would impose on us for what they are not, even the merit which they have. This is the comedy of artificial life, of wit and satire. Shakespeare represents these two kinds of misrepresentation in Twelfth Night. Sir Toby, with his troupe, provokes Malvolio's mis-guided desires by misrepresenting Olivia's false epistle. Misrepresentation debunks by its very falsity Malvolio's “false” desire to marry up and dominate over his household. Here misrepresentation represents the wrongness of desire stimulated by it.Malvolio is both a kind of an actor and the audience caught up by the air of pestilent performances in the theater. Malvolio's humorous and over-ruling desire is condemned as madness. Unlike Malvolio, Viola actively misrepresents herself as Caesario. By usurping her gender and identity, she also provokes Olivia's desire of love and derives her out of her autic self. Viola's virtue lies not in her birth but in her performances and her marrriage represents the very power of representation. Thus Shakespeare represents by his misrepresentations in Twelfth Night the emergent social mobility and flexibility of men's identity. Imaginative literature, Misrepresentation is simultaneously a grace and a curse as its literary history shows.

본 연구에서는 스마트폰 소비자들이 추구하는 편익을 바탕으로 스마트폰 소비자들에 대한 세분시장을 파악하고, 각 스마트폰 세분시장에서 중요하게 생각하는 속성을 분석하였다. 연구결과 스마트폰 소비자들은 실용적 편익과 쾌락적 편익과 함께 네트워크 편익을 추구하고 있으며, 추구편익에 따라 스마트폰 소비자들을 모든 편익 추구 집단, 실용적 네트워크 편익 추구 집단, 쾌락적 네트워크 편익 추구 집단, 비네트워크 편익 추구 집단 등의 4가지 군집으로 구분할 수 있었다. 4가지 추구편익으로 세분화된 스마트폰 소비자 집단별로 중요시 하는 스마트폰 속성들은 단말기 가격, 단말기 브랜드, 단말기 반응속도, 어플리케이션 활용, 요금제, 무선인터넷 연결품질, 동일한 통신사 가입자 수 등의 7가지 스마트폰 주요 속성들 중에서도 다양하게 차이가 나는 것을 확인할 수 있었다. 본 연구는 스마트폰 소비자들이 추구하는 편익의 유형을 분석하여 이제까지 제품에 대한 추구편익의 유형으로 널리 인식되어 온 실용적 편익과 쾌락적 편익의 2가지 유형에 추가하여 네트워크 편익이 중요하게 구분되어 존재하고 있음을 확인한 것, 실용적 편익, 쾌락적 편익 및 네트워크 편익을 추구하는 수준에 따라 특징적으로 구분될 수 있는 스마트폰 소비자 집단을 세분화 하여 각 세분 집단별 차별화 수단을 속성 차원에서 제시한 것 등에서 의의를 찾을 수 있다. This study aims to classify the pursuit benefits of smart-phone users, to find smart-phone market segments by pursuit benefits, and to analyze the relative importances of smart-phone attributes according to the smart-phone market segments. As a result, we found that smartphone users are pursuing the network benefit as well as the two traditional benefits (the utilitarian benefit and the hedonic benefit). According to the levels of these three pursuit benefits, smart-phone users can be classified into four segments : All Benefits Cluster, Utilitarian-Network Benefits Cluster, Hedonic-Network Benefits Cluster, and Non-Network Benefits Cluster. We also verified that, according to the four smart-phone user segments by the pursuit benefits, there exist significant differences in relative importances of the seven smart-phone attributes : hand-set price, hand-set brand, hand-set speed, applications, tariff, mobile internet quality, and number of same service users.

This research examined the effects of an emotion coaching group counselling program on middle school students with high depression, anxiety and suicide consideration. The emotion coaching group counselling program is one, based on emotion coaching, in which art therapy and reading therapy are carried out side by side. The subject of this research was female students, whose level of depression, anxiety and suicide was higher than average, out of 2nd graders of J middle school in Daegu. They were divided into Experimental group(N=6) and control group(N=6). The session was composed of 10 sessions in total, each for 40 minutes at the same time every week. Post and preliminary tests were conducted for the inspection of effects using measurements of depression, anxiety, suicide and self-esteem of which the reliability and validity were verified. SPSS 20.0 was used for data analysis. The results of this study are as follows. First, the experimental group students, who took part in the emotion coaching group counselling program, showed a significantly reduced depression compared to the control group students. Second, the experimental group students showed a significantly reduced anxiety compared to the control group students. Third, the experimental group students showed a significantly reduced suicidal consideration compared to the control group students. Fourth, the experimental group students showed an increased self-esteem compared to the control group students. In conclusion, the emotion coaching group counselling of this study was found out to be efficient in reducing the depression, anxiety and suicide consideration of students and raising the self-esteem.
