PURPOSE: The purpose of this study was to evaluate the factors that affected self efficacy, social support and learning achievement in the web-based learning of graduate school students. METHODS: The data were collected from 79 nurses in a web-based learning. A self-reported questionnaire was used to assess the level of self-efficacy, social support and learning achievement. RESULTS: The learning achievement was significantly improved to 4.05 points after web-based learning compared to 2.69 points before web-based learning, and all other items were also improved. Self-efficacy was improved to 3.91 points from 3.66 points after web-based learning and so was social support to 4.18 points from 3.94 points. Fatigue and stress among health behavior characteristics were significantly decreased after web-based learning. CONCLUSION: This study shows that the web-based learning improved self-efficacy and social support of the students. And self-efficacy was an important factor in learning achievement. It is necessary to develop a strategy to improve self-efficacy as well as to manage social support for increasing interactions among the nurses in a web-based learning.

LPS and IFN-r induce nitric oxide synthase in macrophages and the resultant NO causes apoptotic cell death in the activated macrophages. NO production and apoptosis were inhibited by N-monomethyl L-arginine (NMMA), a competitive inhibitor of NO synthase. To study the role of BCL-X proteins, RAW 264.7 cells were transfected with the expression vectors with human bcl-Xl or bcl-Xs cDNAs, respectively. Stable transfectants were selected and confirmed by RT-PCR. NO production in response to LPS and IFN-r caused apoptosis in RAW 264.7 cells and vector transfected control cells within 24 hr. Both NO production and apoptosis were inhibited by N(G)-monomethyl L-arginine (NMMA). In contrast, bcl-Xs transfectant appeared slightly susceptible and bcl-X(L)< transfectant appeared slightly resistant, although NO production was similar to control cells. These results suggest that bcl-X proteins play roles in both positive and negative regulation of apoptosis induced by NO.

The purpose of this study was designed to develope and test the structural model that explains alcohol consumption behaviors among university students in Republic of Korea. The hypothetical model was constructed on the basis of the literature review and Pender's Health promotion model. Data was collected from questionnaires from 512 university students in Republic of Korea, from August to September, 2000. The reliability of instruments was adequate (Cronbach's alpha= .69-.90). Data analysis was done with SAS 6.12 for descriptive statistics and LISREL 8.13 program for covariance structural analysis. The results are as follows;1. The overall fit of the hypothetical model to the data was moderate. Thus it was modified by male and female models.2. The revised model has become parsimonious and had a better fit to the empirical data (male: x2=87.21 p=.00, GFI=.97, AGFI= .94, NFI=.99, NNFI=1.0, CN=619.17, female: x2=49.29 p=.31, GFI=.45, AGFI= .95, NFI=.99, NNFI=1.0, CN=370.02).3. Self-efficacy was most significant factor and personality of novelty seeking, reward compensation, alcohol expectancy and drinking attitude have significant effects on male alcohol consumption behavior. 4. Personality of novelty seeking was most significant factor and personality of harm avoidance, friend influence, self-efficacies, alcohol expectancy and drinking attitude have significant effects on female alcohol consumption behavior.

PURPOSE: This study is to conduct a comparative analysis of influencing factors on the experience of mammography targeting ordinary women and outpatients. METHODS: The target subjects were 116 ordinary women and 105 outpatients, and the study period was around 8 months from May to December. RESULTS: When mammography experience was examined, it was found that mammography experience was conducted in 44.8% of ordinary women and 59.0% of outpatients, but this study showed that there was a statistically significant difference. When the relation between the characteristics of the targeted objects and the experience of mammography was examined, it was found that ordinary women have a lot of experience when they have regular exercises and a high health belief. On the other hand, in case of outpatients. mammography experience was more frequent in the older group. In addition, outpatients had experiences in breast-related diseases or high self-efficacy. It was also found that the influencing factors on the experience of mammography were a high health belief in case of ordinary women, and old ages and high self-efficacy in case of outpatients. CONCLUSIONS: In order to increase the rate of conducting early detection behavior for mammography, it is needed to conduct an intervention that increases health belief for ordinary women, while it is effective to conduct an intervention that increases self-efficacy for outpatients.

Sunlight is one of the well-established factors which play key roles in the induction and exacerbation of lupus erythematosus. In two patients of discoid lupus erythematosus, we have experimentally reproduced skin lesions by provocative phototesting. Both UVA (100 joules/cm²) and UVB (80 millijoules/cm²) radiation induced the skin lesions. The reproduced skin lesions were clinically and histopathologically consistent with lupus erythematosus.

BACKGROUND: Recent evidences suggest that anesthetic action within the spinal cord is important in suppressing somatic responses to painful stimuli. Intrathecal endothelin-1 (ET-1) is known to have antinociceptive effect. The purpose of this experiment was to determine whether intrathecal ET-1 may influence the minimum alveolar concentration (MAC) of isoflurane in rats and access the role of the spinal cord as the sites of anesthetic action in blocking somatic responsiveness. METHODS: In Sprague-Dawley rats fitted with an indwelling intrathecal catheter, we determined the MAC of isoflurane using a tail-clamp technique as a painful stimulus, combined with end-tidal anesthetic sampling. In experiment 1, the control MAC was determined and changes of control MAC were observed after intrathecal ET-1 (4x10-2 nmol, 4x10-3 nmol) administration. In experiment 2, we observed the effects of L or N type Ca++ channel blocker such as verapamil (50 g) or W-conotoxin (0.5 g) on the MAC after measurement of the control MAC. In experiment 3, after measurement of the control MAC, ET-1 (10-2 nmol) was administered intrathecally and the MAC was determined again. Next, intrathecal verapamil (50 g) or W-conotoxin (0.5 g) was injected. After that, the MAC was determined again. RESULTS: In experiment 1, ET-1 decreased the MAC of isoflurane and its effect was sustained over 2 hours. In experiment 2, the MAC, determined following administration of verapamil or W-conotoxin, was not different from that of the control. In experiment 3, the MAC was decreased after ET-1 administration and then increased following injection of verapamil or W-conotoxin. CONCLUSIONS: These results suggested that ET-1, in relation to calcium, might play an important role in determining the MAC of isoflurane in the spinal cord.

Intravenous lidocaine has been used for attenuating cardiovascular responses to endotracheal intubation. To determine the optimal time of administration of lidocaine for attenuating hemodynamic changes induced by intubation, 100 patients were allocated randomly to a control group (without lidocaine) or four treated groups (with lidocaine). Lidocaine 1.5 mg/kg was administered intravenously at 60 (Group 2), 90 (Group 3), 120 (Group 4) and 180 seconds (Group 5) before intubation. Arterial pressure (systolic, mean and diastolic), heart rate and rate-pressure product (RPP) were measured before induction, after lidocaine injection, immediatly before intubation, immediately and 5 minutes after intubation. After intubation, arterial pressure, heart rate and RPP increased significantly in every study groups. In group 2 and 3, however, such changes were attenuated significantly, Postintubation elevation of systolic blood pressure, mean arterial pressure and RPP were effectively prevented in group 2 and 3. Lidocaine effect on diastolic pressure was observed only in group 3. Changes of heart rate were not affected with lidocaine adminiistration. In Group 4 and Group 5, this effect was not observed. In diastolic pressure, suppressive effect of lidocaine in increasing of blood pressure and RPP was observed in Group 3 significantly, but not in Group 2, Group 3 and Group 5. Changes of heart rate show that in all groups injected lidocaine (Group 2,3,4,5) significantly suppressive effect was not observed as compared with control group. These results suggest that intravenous lidocaine (1.5 mg/kg), 60-90 second prior to intubation attenuate hemodynamic responses induced by intubation.

PURPOSE: To report two cases of successful acellular dermal allograft transplantation for scleromalacia following pterygium excision. CASE SUMMARY: A 72-year-old female patient developed scleromalacia on the nasal side of the right eye, and a 79-year-old female patient developed scleromalacia with inflammation on the nasal side of the left eye. They had previous histories of pterigia removal on the sites of scleromalacia. Acellular dermal allograft (AlloDerm(R), Lifecell, NJ, USA) transplantations were done. After the operations, inflammation and pain ameliorated and the grafts survived without any particular complications. CONCLUSIONS: In treating scleromalacia, the transplantation of acellular dermal allografts produced relatively satisfactory results without undesirable problems commonly encountered when using conventional materials.

Sixty healthy adult patients undergoing general anesthesia for elective surgery were randomly allocated to three group(n = 20), and their EMG response(twitch height) of the adductor digiti mini muscle(hypothena) to TOF stimulation of ulnar nerve by Datex relaxograph was monitored. The patients were received a bolus injection of vecuronium(0.1mg/kg) alone in group I, vecuronium(0.1 mg/kg) after 25-50% recovery from SCh(l mg/kg) in group II, and the mixed injection of SCh(1 mg/kg) and vecuronium(O.I mg/kg) in group III. The onset time(mean SEM) of effect of vecuronium(0.1 mg/kg) in group II(2.2+/-0.4 min) and group III(1.7+/-0.2 min) significantly was shorten when compared with a bolus injection of vecuronium alone in group(4.4+/-0,4 min)(p<0.05). The duration(mean+/-SEM) of vecuronium(0.1 mg/kg), however, had no significant differences among three group. It was 33+/-2 min in group I, 39+/-3 min in group II, and 34+/-2 min in group III. The potency of twitch height depression of vecuronium(0.1 mg/kg) was increased significantly following preinjection of SCh(1 mg/kg) and at the mixed injection of SCh and vecuronium The intensity of fasciculation induced by SCh was not affected at the mixed injection of vecuronium in group III. The peak increases in arterial pressare and heart rate on the endotracheal intubation were attenuated significantly at the mixed injection of SCh (1 mg/kg) and vecuronium(0.1 mg/kg) when compared with its effect of SCh (1 mg/kg) in group II(p<0.05).
