장윤식,황승순,박동원 동아대학교 환경문제연구소 2000 硏究報告 Vol.23 No.1

We studied on the phase equilibria of quaternary liquid-liquid extraction system containing acetic acid-water-binary solvent at 25℃, MEK-butyl acetate were used as binary solvents. Binodal curve, tie-line, distribution and selectivity for each quaternary system have been determined in order to investigate the effect of using binary solvent in extracting acetic acid from aqueous solution. And these experimental tie-line data were also compared with the values predicted by WAC model. It was shown that UNIFAC model is capable of predicting the tie-line in these quaternary systems within an average RSDM of 3.76 mol%.

영어 수동구문의 형식의미론적 분석

張東植 순천대학교 어학연구소 1990 어학연구 Vol.2 No.-

In this paper, an attempt was made to provide a uniform treatment of passive constructions in English. In order to solve this problem, I provide three approaches. These are sentential, phrasal and lexical approaches. In chapter Ⅱ, some problems are suggested when sentential and phrasal approaches are adopted. When sentential approach is adopted, verbs and the past participle form of the verbs should be explained separately. In the case of adopting phrasal approach, two rules are needed to explain passive constructions in English. But considering the aims of linguistic research, - that is to seek universality and simplicity in grammar, there are many strong points in adopting lexical approach. By applying this method, auxiliary 'be', past participle and by phrase can be explained uniformly. so I adopted Freidin's syntactic arguments of passives and accommodate them with the semantic translations within the framework of Montague Grammar. Also by this method not only the sentences with univeral and exsistential quantifiers but also the sentences with verb phrases can be explained without ambiguity. The details of the process are shown in chapter Ⅲ. But more studies are needed to show whether this process can be applied in progressive form and more studies on 'be' verb are needed to show that passive constructions are the same as the SVC form in school grammar. If these problems are solved, we can take a uniform treatment of the 'be' verb.

초산-물-용제계의 액-액평형에 관한 연구

장윤식,박동원 동아대학교 생산기술연구소 2001 生産技術硏究所硏究論文集 Vol.6 No.1

Due to the rising cost of energy, new separation processes based on extraction are becoming more attractive than before. Thus, the need for claculating and predicting liquid-liquid equilibria(LLE) compositions has very much increased. The purpose of this study is to determine the binodal curves, tie-lines, plait-point, distribution and selectivity for the ternary systems of acetic acid-water with methyl ethyl ketone(MEK), methyl isobutyl ketone(MBK), ethylacetate(EAc), butylacetate(BAc), toluene and o-xylene as solvents at 25℃. And those tie-line data were used to examine thermodynamic consistency. The experimental tie-line data were correlated with NRTL and UNIQUAC models.

정신분열병 입원 환자에서 단축형 증상관리 훈련의 효과:예비적 연구

최충식,채정호,우동원,최영희,함웅,이규항,장미화 대한신경정신의학회 2001 신경정신의학 Vol.40 No.1

연구목적: 정신분열병 환자에서의 재활치료는 개인의 극복 기술과 능력을 향상시키고 재발을 유발시킬 수 있는 스트레스의 부정적인 영향을 중화시킴으로써 질병의 만성화를 막고 사회기능을 호전시킬 수 있기에 점차 그 중요성이 대두되고 있다. 본 연구는 만성 정신분열병 입원 환자에서 재활치료의 하나인 단축형 증상관리 훈련이 정신장애에 대한 자기 인식에 미치는 효능을 알아보기 위하여 시행되었다. 방법: 정신분열병으로 진단받고 입원 중인 환자들에게 재발경고징후를 규명하는 것, 재발경고징후를 관리하는 것, 지속증상을 극복하는 것, 술과 불법 약물을 피하는 것 등으로 구성된 승인-UCLA 사회기술 및 독립적인 생활기술훈련 단위 중 증상관리단위를 기초로 한국실정에 맞게 축약한 증산관리 훈련을 주 1회, 60분씩, 4∼5주간 실시하였고 실시 전후에 전신장애 비인식 평가 척도(Scale to Assess Unawareness ofMental Disorder; 이하 SUMD)로 자신의 정신장애에 대한 인식을 평가하였으며 임상적 전반적 인상(Clinical Global Impression;이하 CGI)로 임상 상태를 조사하였고 각 인구학적 변인들을 조사하였다. 결과: 환자 30명이 훈련을 완수하였으며 이들의 평균 연령은 36.6±7.6세였고 남자가 14명(46.7%), 여자가16명(53.3%)이었다. SUMD 점수는 훈련 전 16.9±4.0점에서 훈련 후 12.9±4.2점으로 유의하게 줄어 정신장애에 대한 자기 인식 정도가 향상되었으며(p<0.01), CGI도 훈련전의 3.7±0.9점에서 훈련 후 2.8±0.8점으로 유의하게 호전되었다(p<0.01). 환자의 연령, 발병시 연령, 유병 기간, 입원 기간, 항정신병약물 사용 용량, 교육 정도, CGI로 평가한 임상 상태등은 정신장애의 자기 인식 정도와는 관련성이 없었다. 결론: 정신분열병 입원 환자에서 단축형 증상관리 훈련은 정신장애에 대한 자기 인식을 증가시킬 수 있는 방법이 될 가능성을 확인하였으며 이 방법이 정신분열병 재활치료의 중요한 요소가 될 수 있음을 알 수 있었다. Objectives : The purpose of this study was to examine whether Symptom Management Module-Korean Brief Version(SMM-B) is effective as a psychosocial treatment of the inpat-ients with chronic schizophrenia. We also questioned which of demographic and clinical characteristics could be predictors of differential treatment response. Methods : The subjects were composed of 30 inpatients with chronic schizophrenia, who were trained with weekly session of SMM-B for 5 weeks. Before and after the training, the level of psychopathology, knowledge about schizophrenia were assessed as dependent variables by using Clinical Global Impression(CGI) and Scale to Assess Unawareness of Mental Disorder(SUMD). Results : Overall, patients showed improvement over the treatment period on psychopath-ology as well as knowledge about psychosis. Total scores of SUMD were changed from 16.9±4.0 before training to 12.9±4.2 after training(p<0.01) and scores of CGI were improved from 3.7±0.9 to 2.8±0.8<p<0.01). Howver age, gender, years of education, age of onset, duration of illness, duration of admission, numbers of psychiatric admission, and clinical status evaluated by CGI were not correlated with unawareness of psychosis. Conclusion : These results suggest that SMM-B could be a reliable method to improve self-aw-areness of psychosis in patients whth chronic schizophrenia and one of important elements in rehabilitation.

Due to the rising cost of energy, new separation processes based on extraction are becoming more attractive than before. Thus, the need for calculating and predicting liquid-liquid equilibria(LLE) compositions has very much increased. The purpose of this study is to determine and describe LLE data for the quaternary system containing acetic acid aqueous solution and solvent at 25℃. We investigated that the selection of the optimum solvent to separate acetic acid from aqueous solution and compared with ternary and quaternary LLE including binary solvent also.

Gas metal arc welding process has been chosen as a metal joining technique due to the wide range of usable applications, cheap consumables and easy handling. Three main indicators such as arc voltage, welding speed and welding current have a big influence in the quality welding. Since all these factors affect the quality of the welded joining parts, the effect of these parameters was investigated experimentally. In this paper, an attempt has been made to develop the predicted models (quadratic and cubic) for bead height using genetic algorithm. Performance of the developed models were proved to be compared to the regression equation.
