A open- pore polyuretane foam was investigated as adsorbent for organic pollutants. The distribution coefficients have been determined by batch method to study the adsorption mechanism of organic compounds on open- pore polyurethanc foam by changing pH and methanol percentage of the medium. It seems that the adsorption behaviors of organic compounds on open- pore polyurethane foam are due to van der waals attraction, dipole- dipole interaction and hydrogen bonding additionally between the organic molecule and foam matrix in comparison with Amberlite XAD- 2.

Chromatographic retention behavior and separation of various phenol derivatives on a Partisil 10 ODS 3 column-with mobile phase containing a-cyclodextrin-were systematically studied. The decrease in k' values caused by the addition of cyclodextrins in the mobile phase was based on the formation of an inclusion complex, resulting in weakening of the hydrophobic interaction between solutes and the stationary phase. The content of the organic solvent in the mobile phase also influenced k' values of the solutes, and k' values increased with a decrease of the content of organic solvent in the mobile phase. A simple equation has been derived that reveals the hyperbolic dependence of the capacity factor on the total concentration of cyclodextrin. A plot of the reciprocal of the capacity factor against (CD)_(T) gives a straight line and the dissociation constant, K_(p), of the inclusion complex can be calculated from the slope. The capacity factor decreased with increasing temperature. The enthalpy was calculated from the slope of van't Hoff plots. Under optimum conditions, some mixtures of phenol derivatives were able to separated successfully

Costume has been steadily changed and developed, not only creating the mode, but also fading it according to the social change of many historical events the French Revolution(1789) was a very meaningful on in reforming costume conspicuously as well as in establishing the modern European history. Accordingly this study aims to present how costume, headdress, hat, shoes, and ornaments, etc. from the Rococo<1714~1789> to the Empire<1789~1815>. 1. In clothes, culottes, the short trousers was changed into today's pantaloon through sans-culottes, merveilleuse clothes into highwaist, chemise into Y-shirt, cravate into necktie and veste into waistcoat. Aristocratic costume disappeared ; and the civil one led the major-style while redingote provided variant designs for women overcoat. And in colour the conventional black vanished, namely the democratization of clothes was practiced. 2. In hairdress and hat, men had short hair, and the simple formed-hat appeared, for example chapeau with high crown ;it showed the pragmatic tendency. In women's hair and hat, the archaic style titus and short curled-hair were prevalent, which was the resurrection of the old fashion. And oriental shawl and luxurious turban imported through Napoleonic external wars were in mode, which showed the influence on the costume of the political condition. 3. In shoes, men wore comfortable low-heeled pumpus and boots suiting for their clothes. Women wore escarpin comfortable in wearing and Greek styled-shoes, but in fact there was no great change in comparison with clothes or hairdress. 4. In ornaments, watchpocket, seal which hung under the watchpocket and gloves were men's major accessories. Women carried the portable folding-fan with them, and used to wear gloves becoming to shoes. 5. In clothes, practical ones such as wool and textile were favored because of the economically poor situation just after the Revolution. However, after Napoleon's accession to the thron material and colour of clothes become colourful and bright according the the internal reformation and beautification of Paris. These phenomena imply that economical conditions make materials of clothes simple or exuberant. And after the French Revolution the democratization of clothes was practiced and civil costume oriented to the new mode was fixed, while the aristocratic tendency was demolished. In short costume after the Revolution became the turning point of modernization.

Chromatographic retention behavior and separation of various phenol derivatives on a Partisil 10 ODS 3 column- with mobile phase containing α-cyclodextrin-were systematically studied. The decrease in k' values caused by the addition of cyclodextrins in the mobile phase was based on the formation of an inclusion complex, resulting in weakening of the hydrophobic interaction between solutes and the stationary phases. The content of the orgainic solvent in the mobile phase also influenced k' values of the solutes, and k' values increased with a decrease of the content of organic solvent in the mobile phase. A simple equation has been drived that reveals the hyperbolic dependence of the capacity factor on the total concentration of cyclodextrin. A plot of the reciprocal of the capacity factor against [CD]_T gives a straight line and the dissociation constant. K_D, of the inclusion complex can be calculated from the slope. The capacity factor decreased with increasing temperature. The enthalpy was calculated from the slope of van't Hoff plots. Under optimum conditions, some mixtures of phenol derivatives were able to separated successfully.

본 연구에서는 이미 학교 현장에서 활성화되고 있는 ICT 활용수업에서 고려해야 할 교수방식으로 교수자 통제방식과 학습자 통제 방식을 설정하고, 이러한 수업통제방식에 따라 주요한 학습자 특성변인인 사전지식과 컴퓨터에 대한 자기효능감이 학습자의 학업성취 및 만족도에 미치게 되는 영향이 어떻게 달라지는지를 검증해 봄으로써 학습자 특성을 고려한 ICT 자료를 활용한 수업의 교수 전략 및 지침을 제공하고자 하였다. 연구 결과, 수업통제방식과 사전지식, 수업통제방식과 컴퓨터에 대한 자기효능감의 상호작용은 성취도 및 만족도에 유의미한 영향을 미치지 못했고, 오직 세 변인의 상호작용만이 성취도 및 만족도에 유의미한 영향을 미치는 것으로 나타났다. 또한, 성취도에 영향을 미치는 변인 중에서 가장 큰 영향을 미치는 변인은 사전지식이며, 만족도에 가장 큰 영향을 미치는 변인은 컴퓨터에 대한 자기효능감이었다. 이러한 결과는 ICT 활용 수업에서 수업통제방식과 사전지식, 컴퓨터에 대한 자기효능감의 상호작용이 이들 중 어느 한 변인을 제거하는 것과 비교해 성취도 및 만족도에 미치는 영향이 더 크다는 것을 보여줌으로써, 컴퓨터와 학습상황, 학습자의 특성 등을 포함하는 다양한 요인들에 대한 복합적인 고려가 없이 이루어지는 집합적인 ICT의 도입은 기대하는 학습효과를 가져오지 못할 수 있음을 시사한다. The purpose of this study is to explore the relationship between learner characteristics(prior knowledge, computer self-efficacy) and achievement and satisfaction in an environment where ICT is applied to different instructional controls(instructor control, learner control). The idea which supports the rationale of this study could be drawn either from Jonassen(1999) or Kozma(1994) who emphasized the role of the learner itself for learning to take place in ICT environments. To this purpose the following research questions were investigated. The results of this study were summarized as follows: First, there was a significant statistical correlation between prior knowledge and computer self-efficay, r(66)=.448, p < .01. Instructional control, the main treatment of this study, however, had no significant statistical correlation with any other variances(p>.05). Specially, Prior knowledge showed strongest interaction with achievement, r(66)=.569, p<.01, while computer self-efficacy showed strongest interaction with satisfaction, r(66)=.489, p < .01. Second, there was little significant statistical differences between prior knowledge and instructional control, and computer self-efficacy and instructional control. Instead, interaction of all three variances had significant statistical differences in achievement(β=.277, p<.05). However, this interaction was less effective than each variance- prior knowledge, computer self-efficacy that affect the achievement. Third, except interaction of all three variances(β=.323, p<.05), there was little significant statistical differences between prior knowledge and instructional control, and computer self-efficacy and instructional control, as same as second result. It could be inferred from the results of the study that the interaction of various variances including instructional control, prior knowledge, and computer self-efficacy can affect the achievement or satisfaction. As the existing research results showed, there are various results according which variables are considered. Also, based upon these results, one may rightly argue that the instructional design process must include alternative strategies in which the nature of the task is taken into account at different learner characteristics.

purpose: This study was conducted to describe qualitatively the entities of nurse's experiences in general hospitals and to suggest basic data guiding research on developing Standards of clinical nursing practice in Korea. Method: Fourteen nurses working at general hospitals with over 300 beds in Seoul were interviewed in-depth until saturation using tape-recorders and transcription. Result: The central theme of clinical nursing practice experienced by subjects was "being with clients" that means accepting client's personal character, solving client's needs and providing client-centered nursing. A also "being with clients" was felt to be the responsibility of nurses which was learned from their nursing schools. The nursing strategies performed in order to be with patients were proving skillful nursing techniques, accepting, educating, emotional support, advocating, and self-reflecting, the subjects experienced somewhat problematic affects such as difficulties in interpersonal relationship, work overload, negative image of nursing, deficit of self-confidence for nursing actions, poor working conditions, and unfair treatment. Nurses at the hospital practiced with pride when they felt that they were accepted by clients. Conclusion: Further research is needed to analysis problems in clinical practice and the comparison of nurses' experiences of clinical practice, with nurses' experiences in various settings.

Purpose: The purpose of the study was to forecast manpower by building the nursing manpower-staffing model(surgical-medical nursing unite). Method: The system dynamics approach was adapted to build a simulation model for calculating medical-surgical nursing manpower-staffing. The model was built up on Venism 5.0b DSS. Result: The results in the basic circumstance are in following. The level of nursing service quality, patientsatisfaction, and nurse job satisfaction maintains higher at medical-surgical nursing unit of the tertiary hospitals with the ratio of bed to nurse 2.5:1-3.0:1 than at any other situations. The level of nursing service quality, patient satisfaction, and nurse job satisfaction maintains higher at madical nursing unit of the secontary hospotals with the ratio of bed to nurse 3.0:1 and at surgical nursing unit of the secondary hospitals with the ratio of bed to nurse 3.0:1-3.5:1 than at any other situations in the fundamental from. The results in the simulation circumstance are in following, As author raises the operating rate of bed into 95-100%, and cut skilled nursing staff down, the level of nursing-service quality, patient satisfaction, and nurse job satisfaction drops slightly. Conclusion: In terms of economic efficiency on tertiary hospotals, the ratio of bed to nurse for the best reasonable medical-surgical nursing manpower-staffing is 3.0:1. In terms of economic efficiency on secondary hospitals, the ratio of bed to nurse for the best reasonable medical nursing manpower-staffing is 3.0:1 and surgical nursing manpower-staffing is 3.5:1

This cross-sectional investigation evaluated the trend of psychological changes by Qi-training using a self-report inventory of emotional distress, Symptom Check List-90-Revision (SCL-90-R). Forty-one normal healthy subjects (mean age: 21.0±5.4) and one hundred-twenty-three Qi-trainees (divided into three groups, primary, middle and high level) participated in this study. Primary level group has received 1-4 months Qi-training (mean age: 22.0±7.8, n = 41); middle level group has 5-12 months Qi-training (mean age: 20.0±7.8, n = 41); and high level group has more than 1 year Qi-training (mean age: 22.7± 6.7, n = 41). Our results show that all of psychologucal symptom scales of Qi-trainees over lyear were significantly lower scores compared to controls. In addition, high level group had lower global indexes scores than control. A significant negative correlation was found between the Qi-training period and all SCL-90-R subscales except phobic anxiety. These results suggest that Qi-training is effective in protection as well as reduction of psychological symptomatology.
