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 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.

The purpose of this study was to investigate the effects of dietary purple sweet potato(lpomoea batatas) powder on serum lipid levels and antioxidative enzymes in normal and pretective effect on hepatotoxicity rats induced by carbon tetrachlolide. Four groups of rats (3-week-old inbred Sprague-Dawley male rats) were normal rats fed control diet(C)_(1) induced hepatotoxicity rats fed control diet(EC)_(1) normal rats fed purple sweet potato diet(P), and induced hepatotoxicity rats fed purple potato sweet diet(EP). Rats were induced by single injection of 50% carbon tetrachloide(0.1 mL/100 g B.W., i.p.). The rats were fed ad libitum each of the experimental diet for 5 weeks. After 5 weeks the rats were sacrificed and activities of antioxidant enzymes and lipid peroxidation products were determined in their liver homogenates. But serum concentrations of lipid was not significant in all groups. Serum alanine aminotransferase(ALT/GPT) and aspartate aminotransferase(ALT/GPT)of the EC and EP groups were heigher than the C and P groups. The hepatic glucose 6-phosphatase(G9Pase) activity of the group fed purple potato diet(P) was lower than the other groups(p<0.05). However, The glutathione peroxidase(GPx) activities was not statistically different between the groups. Renal glutathione S-transferase(GST) activity of the EC and EP groups were lower than the C and P groups(p<0.05). In conclusion, these results suggest that purple sweet potato is believed to be possible protective effect on hepatotoxicity rats induced by carbon tetrachlolide.

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.

The purpose of this study was to identify the degree of compliance, and its relationship with the health related hardiness, self efficacy of the hemodialysis patients. The data were collected from eighty nine patients on hemodialysis unit from one University hospital and two general hospitals in Seoul from August to September, 1995. The dependent variable for this study was the degree of compliance which was measured with the patients's self-report and biochemical indicators such as the interdialytic weight gain, predialysis serum potassium level and predialysis serum phosphorus level. The instruments used for data collection for this study were as follows: 1) To measure the patient's compliance, the 4-point Lidert type questionnaire was used which was developed by authors based on the literature review, pilot study and content validation by the review of their expertise. 2) The health related hardiness scale, self efficacy scale which were adopted from the previous studies used to measure the independent variables. 3) The data of biochemical indicators were collected from the patient's medical record. The reliability of the scales were ranged between Cronbach's α=.72-.87. The collected data were analyzed with SPSS pc+ program with percentage. ANOVA, Pearson's correlation, Canonical correlation analysis. The results were as follows: 2) There was significant correlation between the health related hardiness and self efficacy(r=-.280, p=.004) and between the compliance with the interdialytic weight gain(r=.346, p=.000) and predialysis phosphours level(r=.218, p=.02). A significant positive canonical correlation was found between the group of independent variables consisted of health related hardiness and self efficacy and the group of dependent variables consisting of patient's compliance and the biochemical indicators(interdialytic weight gain, predialysis derum potassium level and predialysis serum phosphorus level Rc=.444, p=.002). Health related hardness had strongly correlational structure with predialysis serum potassium level and predialysis serum phoshous level. Self efficacy had strongly correlational structure with self reported compliance and interdialytic weight gain in canonical correlational analysis. In the relationship between the group of independent variables and group of dependent variables, the main influencing factors were self efficacy and self reported compliance(canonical weight: -.887, -.695). From the above results, it can be concluded thqt; Self efficacy was found as a potent predictor of the compliance in hemodiaysis patients. These results suggest that feasibility of the cognitive approach for nursing intervention such as increasing the level of self efficacy.

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.

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
