환경오염 물질 제거를 위한 친환경 촉매 개발 및 응용

이선화 서울산업대학원 산업대학원 2010 국내석사

유기 반응들 중에는 자연적인 현상으로써 쉽게 이루어지는 반응이 있는가 하면, 물리적 혹은 화학적 힘을 가해 추가적인 에너지를 공급하는 조건 하에서만 반응이 이루어지는 경우가 있다. 후자의 경우 다양한 반응 촉매를 사용하여 반응의 효율을 높이는 방법을 주로 사용하고 있는데, 이렇듯 어려운 반응을 쉽게 이루어지게 하는 촉매의 개발과 적용이 실험실 내 연구 분야뿐만 아니라 화학 산업 분야에서도 가장 중요한 과제 중 하나로 꼽히고 있다. 촉매 반응계에는 크게 균일 촉매계와 불균일 촉매계로 나누어진다. 균일 촉매는 금속을 함유하고 있는 촉매 물질이 반응 용매에 용해되어 쉽게 균일화 되는 촉매를 가리키는 것이다. 반면 불균일 촉매는 금속을 함유하고 있는 촉매 물질이 반응 용매에 용해되지 않아 불균일 상으로 존재하는 촉매를 가리킨다. 균일 촉매는 대부분 반응성과 선택성이 불균일 촉매에 비해 탁월한 것으로 알려져 있다. 따라서 고부가가치의 유기 화합물을 합성하는데 매우 우수한 촉매 역할을 한다. 불균일 촉매는 균일 촉매에 비해 촉매 능력은 조금 떨어지지만, 간단한 여과와 세척 작업을 통해 촉매를 회수하여 재사용 하는 과정이 가능하다. 즉 친환경적이며 경제적이라고 할 수 있기 때문에 주로 산업적인 화학물질의 대량 제조에 사용된다. 본 연구에서는 위의 두 가지 촉매의 장단점을 이용하여 실험을 진행하고, 그에 따른 결과를 통해 촉매에 의한 효과를 분석하는 것에 초점을 맞추었다. Part Ⅰ: In chemical industry, heterogeneous catalysts appear very attractive because of their recyclability. They are absolutely useful catalysts because they could be easily separated from the reaction products. On the other hand, homogeneous catalysts usually have outstanding catalytic activity and selectivity. Therefore these catalysts definitely useful in the field of fine chemistry. We examined the catalytic activity of many polymers that have various structures. They were obtained by self-assembly in various solvent conditions and contained different metal ions and organic ligands. We have examined the catalytic activity of many polymers for transesterification of ester. PartⅡ: The epoxidation of olefins into the corresponding epoxide plays an important role in organic synthesis. We have developed highly efficient catalytic epoxidation of olefins with MCPBA and PhIO catalyzed by Mn clusters, [{Mn(Saloph)H2O}4Re4Te4(CN)12] and [{Mn(Saloph)H2O}4Re4Se4(CN)12]. Hydrocarbon oxidation by these catalysts was proposed to involve an Mn(V)-oxo species which is formed upon heterolytic O-O bond cleavage of an Mn-acylperoxo intermediate (Mn-OOC(O)R). Evidence for this Mn(V)-oxo species was derived from H218O-exchange experiments, and the use of peroxyphenylacetic acid (PPAA) as the oxidant. Part Ⅲ: We have examined the epoxidation of cyclohexene into the corresponding epoxide with peroxyphenylacetic acid (PPAA) catalyzed by Mn bpb complexes. Hydrocarbon oxidation by these catalysts was proposed to involve an Mn(V)-oxo species which is formed upon heterolytic O-O bond cleavage of an Mn-acylperoxo intermediate (Mn-OOC(O)R). Evidence for this Mn(V)-oxo species was derived from the use of peroxyphenylacetic acid (PPAA) as the oxidant. And we have examined the epoxidation of olefins and the oxidation of primary alcohols into corresponding compounds with PhIO catalyzed by Co bpb complexes.

The purpose of this study lies in discovering the effect of an English language class based on situated learning theory on learning attitudes. With this goal, the study established the following research questions. First, what kind of change does the English language class based on situated learning theory result in the learning attitude of sixth graders in an elementary school? Second, what kind of change does the English language class based on situated learning theory result in the learning attitude of sixth graders in elementary school according to scholastic achievement level? For this research, the study selected 80 sixth graders in S Elementary School located in Gunsan City, Jeollabuk-do. The selected students were a relatively homogeneous group, and, also, a nature class were composed in the early school year with similar levels of cultural and economic backgrounds. The participating children were made up of 20 male students and 20 female students, totalling 40 students. Meanwhile, the control group consisted of an equal number of students including 20 males and 20 females, totalling 40 students. The pre-learning attitude test for the English language was administered before the beginning of the first class of the research. Then a post-learning attitude test for the English language was performed after offering the English language class for 25 hours during an one week period. The pre-learning attitude test result of the English language found that the average of the control group was 2.28, the test group was 2.74 and thus, the average of the control group was about 0.08 higher. However, the analysis result of the difference in the learning attitude in the English language by groups discovered that there was no significant difference with a significance level of .05. Thus, the two groups may be homogeneous groups in light of learning attitude in the English language before beginning the research. As a result of the post-learning attitude test result in the English language, the average of the control group was 2.84 and the test groups was 3.10, respectively; thus, the average of the test group was 0.26 higher. The difference in the average scores was significant with the level of .001. In other words, the English language based on situated learning theory might have changed the learners' learning attitude in the English language in a positive direction. For the learning attitude test result in the English language of the test group according to the scholastic achievement level, the differences in the averages of pre-and post-test scores between a group with above-average English scores and a group with below-average English scores were .42 and .32, respectively; thus, the group with the above-average English scores were 0.1 higher. Also, as an analysis result of the difference in the learning attitude in the English language by groups, the difference in the average scores was significant with a significance level of .01. To put it differently, the English language class based on situated learning theory might have changed the learning attitude of students with a higher scholastic achievement level in the English language in a positive direction. That is, as a result of the English language class based on situated learning theory, the students' learning attitudes changed in a positive manner more than that of the class not utilizing the situated learning theory. This means that the class based on the situated learning theory was more effective for students with a higher achievement level. Based on the above results, the study is to propose the following in relation to research. First, it is necessary to conduct in-depth research into the meaning of situated learning, and to develop various class models concerning the English contents of each unit, subsequently. Second, in order to realize situated learning, research needs to be conducted into the utilization of data in each school as well as into the development of English teaching materials.

Identification of Genetic Locus Related to Antivirus Production in Pseudomonas fluorescence strain Gpf01 Against Cucumber mosaic virus

이선화 강원대학교 대학원 2008 국내석사

A Pseudomonas fluorescens strain Gpf01, isolated from ginseng rhizosphere shows antiviral activity against Cucumber mosaic virus, when tested in a local host of CMV, Chenopodium amaranticolor. In previous work, transposon mutant library of Gpf01 was prepared using pGS9::Tn5. It was screened for antiviral activity against CMV. The mutant Gpf01-RS19 was found to have lost the antiviral producing activity. Inverse PCR was used to amplify flanking regions of Tn5 in Gpf01-RS19. We developed primers from the flanking region of Tn5 and screened cosmid library of Gpf01 prepared in pLAFR3 by PCR. We found a cosmid clone pAV1123, harboring 1.2 kb antiviral compound producing (avcP) locus. The cosmid clone pAV1123 containing avcP locus was complmented with a P. fluorescens B16 strain by conjugation. The resultant strain after conjugation showed antiviral activity against CMV-Y. This suggests that, the cosmid pAV1123 contains genes that are required for antiviral activity of P. fluorescens, Gpf01 against CMV-Y. The cosmid pAV1123 was sequenced completely, which contained 25.3 kb insert. The sequence obtained was compared with the sequence database search using BLAST. It was found to show 98% homology with a P. fluorescens strain Pf0-1 (GenBank accession no. CP000094). In order to further characterize the region responsible for the antiviral activity in pAV1123, it was further subcloned. When a clone pPH9, that carried 9.3 kb region of pAV1123, was introduced into antivirus deficient P. fluorescens strain B16, it exhibited antiviral activity. Using Tn3-gus mutagenesis and complementation analysis, it was found that the genes related to antiviral activity production resided in a 9.3 kb HindIII-HindIII fragment of pAV1123, indicating that the plasmid carry essential genes related to antiviral activity. The sequence analysis of the four transconjugants revealed that the antiviral activity related region resides in a 9.3 kb HindIII-HindIII fragment, suggesting that the 9.3 kb HindIII-HindIII region was critical for antiviral activity. A possible transcriptional regulator gene of AsnC family is hypothesized to affect transcription of genes located downstream to it. The functional analysis of the genes involved in 9.3 kb HindIII-HindIII region requires further study. 강원도 홍천의 인삼 근권에서 세균을 분리하고, cucumber mosaic virus (CMV-Y)에 대한 항바이러스 효과를 확인하였다. 분리한 세균의 culture filtrate (CF)를 Chenopodium amaranticolor에 반엽법으로 처리한 결과 CMV-Y의 억제 효과가 있는 Gpf01을 선발 하였다. P. fluorescens Gpf01의 항바이러스 관련 유전자를 탐색하기 위해 pGS9::Tn5를 이용하여 transposon을 제작하였으며, Tn5 mutant 중 CMV-Y에 대해 항바이러스 효과가 억제되는 Gpf01-RS19를 선발하였다. Inverse PCR을 통해 Gpf01-RS19의 Tn5 삽입영역을 분석한 결과 1.5 kb, 0.4 kb의 절편을 증폭하였다. 증폭된 염기서열을 분석하여 primer를 제작하여 P. fluorescens Gpf01 genomic library의 cosmid clone 을 탐색한 결과 1.2 kb의 항바이러스 관련 유전자인 avcP locus를 포함하고 있는 cosmid clone pAV1123을 선발하였다. 항바이러스 관련 cosmid clone인 pAV1123을 항바이러스 효과를 가지지 않는 mutant Gpf01-RS19와 P. fluorescens B16과 complementation하여 항바이러스 효과가 복구되는 것을 확인하였다. Cosmid pAV1123의 항바이러스 관련 영역을 구명하기 위해 전체 염기서열을 분석하였으며, 이를 바탕으로 cosmid pAV1123의 9.3 kb HindIII 절편을 subcloning 하여 pPH9를 선발하였으며, 이를 항바이러스 효과를 가지지 않는 P. fluorescens B16과 complementation한 결과 항바이러스 효과가 복구 되었다. 또한 cosmid pAV1123의 항바이러스 관련 유전자 탐색을 위해 Tn3-gus mutagenesis를 실시하여 8개의 Tn3-gus mutant를 선발하였다. 이 중 P5-P8의 4개의 mutant가 Tn3-gus의 삽입으로 인해 항바이러스 효과가 억제되었다. 염기서열을 분석해 보았을 때 4개의 mutant는 cosmid pAV1123의 9.3 kb HindIII 절편 안에 포함되어 있었다. Blast search를 통해 possible transcriptional regulator AsnC family와 관련된 유전자에 Tn3-gus가 삽입된 것을 확인하였으며, 그 아래쪽의 유전자들도 이에 영향을 받아 항바이러스 능력이 억제된 것으로 추측되었다. 이를 통해 cosmid pAV1123의 9.3 kb HindIII 영역은 P. fluorescens Gpf01이 항바이러스 효과에 중요한 유전적 영역임으로 판단된다.

Anatomical, physical, and mechanical characteristics of seven cultivars of chestnut wood(Castanea crenata Sieb. et Zucc.) in Korea, Tanzawa, Ibuki, Mansung, Arima, Ginyose, Tsukuba, and Riheiguri, were investigated to obtain some valuable information for their possibilities to be used for effective utilization. Solitary pore and figured-porous or ring-porous wood types were observed in wide growth rings, and ring-porous in narrow growth rings. Procumbent type was prevalent in ray cells although upright and square types were scarcely existed. Uniseriate, biseriate, and multiseriate rays were observed in tangential section. Uniseriate ray was abundant near the pith, and biseriate and multiseriate rays were frequently existed near the bark. The occurrence rate of biseriate and multiseriate rays was significantly high in Tanzawa, Ibuki, Mansung and Tsukuba, but was somewhat low in Arima, Ginyose and Riheiguri. In all chestnut cultivars, radial and tangential diameter of vessel element increased with increasing tree age, but the number of vessel per ㎟ decreased. Ray spacing (per ㎜) in cross section from pith to bark showed no significant variation, while the number of ray per ㎟ increased but ray height decreased with the increase of tree age. Fiber and vessel length increased with increasing tree age Green moisture content and density of heartwood were higher than those of sapwood. Tsukuba and Riheiguri had higher green moisture content, and Ibuki and Riheiguri had higher green density than the other chestnut cultivars. Shrinkage and swelling of sapwood were higher than those of heartwood. Especially, radial direction was higher than other directions. Water absorption of sapwood were slightly higher than those of heartwood. Especially, cross section was higher than other sections. Relative crysallinity and crtstallite width of latewood were higher than those of earlywood, and showed no significant variation with tree age. Strengths of compression, bending and shear of heartwood were higher than those of sapwood. Strengths of Ibuki and Riheiguri were higher but Ginyose and Tsukuba were lower than other cultivars. MOEs of compression and bending of heartwood were higher than those of sapwood. MOEs of compression of Ibuki and Riheiguri were higher but Ginyose and Tsukuba were lower than other cultivars, whereas MOEs of bending of Ginyose and Mansung were higher but Ibuki and Riheiguri were lower than other cultivars The results of this study showed difference of anatomical characteristics with tree age, separating index between juvenile and adult wood, also physical and mechanical characteristics as well as identifying chestnut cultivars.

이선화 인천대학교 교육대학원 2014 국내석사

본 연구는 자녀의 부정적 정서에 대한 부모의 비지지적 반응이 아동의 대인관계문제에 미치는 영항을 살피고, 정서표현양가성과 정서인식명확성이 부모의 비지지적 반응과 대인관계문제와의 관계에서 매개변인으로서의 역할을 하는지를 탐색하고자 하였다. 이를 위하여 경기도와 인천에 위치한 초등학교 5,6학년 학생 454명을 대상으로 설문 자료를 수집하였다, 분석결과, 부모의 비지지적 반응과 정서표현양가성, 대인관계문제 간에는 유의한 정적상관 관계가 있었다. 그러나 부모의 비지지적 반응과 정서인식명확성 간에는 유의한 부적상관 관계가 있는 것으로 나타났다. 또한 정서인식명확성과 대인관계문제 간에는 유의한 부적상관이 나타났으며, 정서표현 양가성과 대인관계문제 간에는 유의한 정적상관이 나타났다. 정서표현 양가성과 정서인식명확성은 부모의 비지지적 반응과 대인관계문제와의 관계를 부분매개하였다. 마지막으로 본 연구결과를 중심으로 아동의 대인관계문제를 예방하고 해결하는 데 필요한 시사점과 연구의 함의, 한계를 논의하였다.

감정표현불능증, 무쾌감증과 알코올 중독집단의 자살행동

이선화 충북대학교 2012 국내석사

본 연구의 목적은 감정표현불능증(alexithymia)과 무쾌감증(anhedonia)이 알코올 중독집단의 자살생각 및 자살시도와 관계가 있는지 알아보는 것이다. 감정표현불능증의 감정확인곤란 요인과 감정표현곤란 요인이 자살생각과 자살시도력을 예측하는지, 무쾌감증의 흥미상실 요인과 낮은 긍정정서성 요인이 자살생각과 자살시도력을 예측하는지 각각 살펴보았다. 또한 과거우울증상을 통제한 후에도 감정표현불능증과 무쾌감증이 알코올 중독집단의 자살생각과 자살시도력을 예측하는지 살펴보았다. 본 연구의 참여자는 알코올 관련 장애로 치료를 받고 있는 환자 108명으로서, 병원에 입원한 환자(n = 93, 86%)와 알코올 상담센터에서 치료를 받고 있는 외래 환자(n = 15, 14%)로 구성되었다. 참가자들은 감정표현불능증 척도(TAS-20K), 무쾌감 우울증 척도(Anhedonic Depression Scale), Lifetime 환자건강질문지(Lifetime PHQ-9)와 자살생각 및 자살시도력 등을 묻는 자기 보고식 질문지에 응답하였다. 로지스틱 단순회귀분석 결과, 감정표현불능증의 감정확인곤란 요인과 무쾌감증의 흥미상실 요인이 과거우울증상을 통제한 후에도 자살생각과 자살시도력을 유의미하게 예측하였다. 또한, 인구통계학적 변인 중 혼자 살고 있는 주거 상태가 과거우울증상을 통제한 후에 자살시도력을 가장 강하게 예측하였다. 본 연구의 결과는 알코올 중독집단에서 자신의 감정을 명확하게 인식하지 못하는 특성이나 일상생활에서 흥미나 즐거움을 느끼지 못하는 특성을 가지고 있는 경우와 혼자 거주하는 경우 자살생각과 자살시도의 위험이 증가함을 보여준다. The purpose of the study was to examine the role of alexithymia and anhedonia in suicidal ideation and behavior among alcoholics. It was hypothesized that restrictive emotionality measured by alexithymia characterized by difficulty identify and describing emotions, and anhedonic depression characterized by low positive emotionality and loss of interest would be associated with suicidal ideation and behavior in this population. Further, it was hypothesized that these relationships would remain significant after adjusting for lifetime history of depressive symptoms. A total of 108 participants were recruited from two residential alcohol use treatment hospitals, inpatient unit(n = 93, 86%) and one alcohol counseling center, outpatient unit(n = 15, 14%). The majority of the sample was male(88%). The mean age of the participants was 48.28(SD = 8.78), ranging from 29 to 67. All participants completed self-report measures of Toronto Alexithymia Scale(TAS-20), Anhedonic Depression Scale, and PHQ-9, lifetime version, along with questions of suicidal ideation and attempt. Logistic regression analyses showed that difficulty identifying emotions and loss of interest were significantly associated with both lifetime history of suicidal ideation and attempt even after adjusting for lifetime history of depressive symptoms. Interestingly, living alone was strongly associated with lifetime history of suicide attempt (OR = 4.41, p < .01) but not associated with lifetime history of suicide ideation. The results suggest that risk assessment and prevention effort for this population need to address anhedonic features of depression and living status.
