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

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.

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.

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.

"Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows : 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview. physical measurement, observation were used in 22.8%. 8.2% 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.

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.

As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

This study aims at analyzing the relations among children's affectiveness perspective taking ability, creativity, sociality, casuality, self control ability. The subjects for this study were 160 early children sampled from 4 kindergarten in Busan. The conclusions derived from the result of this study are as follows: First, creativity does not affect sociality of a child. Second, creativity affects physical casuality of a child. Thus, a child with high creativity has higher physical casuality than a child with low creativity. Third, creativity affects affective perspective-taking ability in part. In this case, the fact that this child is the observer or the person itself makes more difference than the simplicity of the environment. Forth, A child who has high total score of creativity in the emotion of pleasure and sadness has low affective perspective-taking ability, and a child who has low total score of creativity in the emotion of anger has lower affective perspective-taking ability than others. However, fear does not affects affective perspective-taking ability. Fifth, creativity does not affect self- control ability of a child.

초등학교 ICT활용수업에서 수업통제방식과 사전지식, 컴퓨터에 대한 자기효능감이 성취도 및 만족도에 미치는 영향

주영주,문자영 이화여자대학교 사범대학 교과교육연구소 2004 교과교육학연구 Vol.8 No.2

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.
