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.

파일 식별과 분석은 컴퓨터 포렌식 수사과정에서 디지털증거 획득 및 증거분석에 중요한 요소이며 지금까지 많은 연구가 진행되었다. 그러나 실행파일의 식별과 분석은 주로 악성코드에 대해 연구되어 왔기 때문에, 저작권침해 사고와 같은 일반적인 실행파일을 세부적으로 분류하고 탐지해야 할 경우에는 기존의 악성코드 분류 방법은 적용되기 어렵다. 따라서, 본 논문에서는 실행파일 헤더내 문서화되지 않은 정보의 유사도 측정에 근거한 비교를 통해 실행파일을 세부적으로 분류할 수 있는 방법을 제시한다. 제안한 방법은 실행파일의 헤더에 포함된 정보를 이용하기 때문에 일반적인 실행파일뿐만 아니라 기존의 악성코드 및 새로운 악성코드와 변종 그리고 실행압축, 코드변형, 가상화 및 난독화된 실행파일 분류에도 활용이 가능하다.

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.
