Purpose: This study was to identify predictors of drug dosage calculation error risk in newly graduated nurses. Methods: A total of 115 newly graduated nurses who passed their employment examination, but didn't work for hospital yet, were recruited from a university hospital. The data were analyzed by descriptive statistics, $X^2$-test, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression using the SPSS 18.0 program. Results: The mean score of 'drug dosage calculation ability' was $0.81{\pm}0.16$ and the mean score of 'certainty of calculation' was $2.95{\pm}0.60$ out of a 5 point scale. The error risk of drug dosage calculation was positively related to anxiety for drug dosage calculations (r=.388, p<.001), but negatively related to interest and confidence in mathematics (r=-.468, p<.001), confidence related to dosage calculations (r=-.426, p<.001). The main predictors of error risk related drug calculations in newly graduated nurses were identified as interest and confidence in mathematics (${\beta}$=-.468, p<.001). This factor explained about 21.9% of the variance in error risk of drug dosage calculation. Conclusion: The strategies used to decrease the error risk related drug dosage calculation such as improving interest and confidence in mathematics should be developed and implemented.

The purpose of this study was to identify nursing needs for hospice patients and their families in order to establish a foundation for appropriate Korean hospice care. To achieve the purpose of this study, 1 interviewed 50 patients who were going to die within 3 or 6 months and 42 family members of these patients who were registered in Pusan National University Hospital Hospice Program. The interview was done in the patient's room using semi-dialog style questionnaire. Data collection was done from March 1, 1999 to September 30. 1999. The important results of this study are summarized as follows : 1. Nursing needs that patients and their families have experienced were classified into six nursing domains; physical, emotional, economic, educational, spiritual and postmortal care. 2. Nursing needs of hospice patients are; pain control(80%), physical comfort(72%), consideration from medical personnel(68%), provision of information(64%), best treatment(60%), help of volunteers(36%), and continuous hospital treatment(32%). 3. Nursing needs of the families are; pain-control in Patients(97.6%), best treatment(97.6%), physical comfort of patients(95.2%), continuous hospital treatment(92.8%), provision of information(80.9%), consideration from medical personnel(76.1%), expectation of recovery(66.6%), emotional support of family(61.9%), and physical comfort of family(40.4%). It is concluded that there is a real difference between the nursing needs of patients and the nursing needs of their families. Therefore we must examine and intervene for the demands of patients and their families using a holistic approach in order to meet their hospice needs.

This study was done to examine the home care service provided by home care nurses and the level of client satisfaction. Data were collected from 110 clients who received the home care service at the P-hospital in Pusan from 23th April, 2001 to 30th November, 2002. The tool for measurement of satisfaction was composed of 16 items and was 4 score scale. Data was analyzed by using SPSS/WIN 10.5 program, the results of this study are summarized as follows; 1) 77.3% among 110 clients were over sixty years old. By the disease pattern. subjects were distributed into cancer(52.7%), cerebro-vascular disease(22.7%) and the others. 36.4% of clients were received home visits from 10 to 20 times by home care nurse. 2) The total number of home care services was 20,828. And most of the clients received the health education and training. 3) The mean score of satisfaction on provided home care services was $3.36\pm0.45$, out of 4. among 16 items. 'The home care nurses were kind enough' was highest ($3.59\pm0.49$), the total level of satisfaction of home care services was very high. with total mean score $53.84\pm7.16$. As mentioned above. the satisfaction level of home care services was very high. so we can except that the prospect of home care services is very challengeable. Therefore. we should try to expand the service recipients with promotional education to the home care clients under the cooperation with medical staff and make more efforts to develop the management system about clients' information. to improve the quality of the service, to assure close ties with the public health centers for the continuous home care service linking.

The piezoelectric single crystals used in piezoelectric transformers have a problem that power transfer capacity is comparatively low due to their high input impedance. In this study, we suggest a method to improve the power transfer capacity by reducing the high input impedance of the piezoelectric single crystal vibrator by connecting a capacitance increasing circuit to the electrical terminals of the piezoelectric single crystal vibrator where the circuit is a GIC (Generalized Impedance Converter) circuit using operational amplifiers. The result of measuring driving characteristics after applying the designed capacitance increasing circuit to the $128^{\circ}$ rotated Y-cut $LiNbO_3$ crystal vibrator confirmed that the input impedance decreased by 25 %, electromechanical coupling factor increased by 30 %, and the power transfer capacity increased by about 17 to 30 times in voltage conversion characteristics.

File identification and analysis is an important process of computer forensics, since the process determines which subjects are necessary to be collected and analyzed as digital evidence. An efficient file classification aids in the file identification, especially in case of copyright infringement where we often have huge amounts of files. A lot of file classification methods have been proposed by far, but they have mostly focused on classifying malicious behaviors based on known information. In copyright infringement cases, we need a different approach since our subject includes not only malicious codes, but also vast number of normal files. In this paper, we propose an efficient file classification method that relies on undocumented information in the header of the PE format files. Out method is useful in copyright infringement cases, being applied to any sort of PE format executable file whether the file is malicious, packed, mutated, transformed, virtualized, obfuscated, or not.

Solvolyses of para-substituted cinnamoyl chlorides in aqueous binary mixtures of acetone, ethanol, methanol were investigated at 25.0$^{\circ}C$. These data were interpreted using the Grunwald-Winstein relationship, Hammett equation, and quantum mechanical model. Grunwald-Winstein plots of the first-order rate constants for para-substituted cinnamoyl chlorides with $Y_{CI}$ showed marked dispersions into three separate curves for the three aqueous mixtures with a large m vaIue for aqueous alcohol solvents. This study has shown that the potential energy surface and quanturm mechanical model predict transition state variation correctly for $S_N1$ like $S_N2$ reaction mechanism of para-substituted cinnamoyl chlorides.

This study purposed to evaluate a $CellPrep^{(R)}$ (CP) of liquid-based cytology (LBC) to search for a less expensive and automated alternative cytologic preparation technique applicable to usually encountered cytologic specimens. Cervicovaginal direct-to-vial split samples from 457 gynecologic patients, 40 body fluid samples, and 34 urine samples were processed with the CP technique and the results were compared with those of currently used $ThinPrep^{(R)}$ (TP) method. Both CP and TP methods provide evenly distributed thin layers of cells with little cellular overlaps or significant obscuring elements in most of cases. Staining quality of both preparations showed a little difference due to the difference of fixative solutions without significant distractions in cytologic interpretation. On the supposition that TP was a gold standard, sensitivity, specificity, positive predictive value, and negative predictive value of CP cytology were 89%, 98%, 86%, and 99% in the cervicovaginal smear, 89%, 82%, 80%, and 90% in body fluid, and all of these values were 100% in urine samples. To testify the availability of immunohistochemistry on CP preparations, cytokeratin, vimentin, and Ki-67 were applied on body fluid specimens, and all of these antibodies were specifically stained on targeted cells. Conclusively, the CP method gave comparable results to those of TP in terms of smear quality and cytologic diagnostic evaluation, and was available on immunohistochemistry. The CP method could offer a cost-effective and automated alternative to the current expensive techniques of liquid-based cytology on popular cytologic materials including cervicovaginal, body fluid, and urine specimens.
